A) The amygdala, which is part of our limbic system and is located at the end of the hippocampus, is important in our fear response and controls the way we react to certain stimuli or events that we perceive as threatening. The hippocampus is a cluster of neurons that functions as the ‘puzzle-piece-assembler’ linking together separated areas of the brain. The hippocampus links various aspects of an experience, such as, the sensations in the body, emotions, thoughts, facts and reflections. The right hippocampus integrates implicit and explicit memories. It weaves emotional and perceptual memory into factual and autobiographical recollections, laying the foundation for our ability to tell our story and to narrate a past experience. Dreams are also one of the important ways to integrate memory and emotion and they occur when cortical inhibition is released enough to allow subcortical limbic and brainstem regions to interact with imagination and feelings. This narrating ability is also dependent on the cerebral cortex, which is the outer wrinkly layer of the brain and is packed tightly with neurons. It is divided into four lobes, the frontal, temporal, parietal and occipital. For instance, the occipital lobe makes sense of visual information. The temporal lobe makes sense of auditory stimuli and evolves around both hearing and selective listening. The cortex is also called the mammalian brain because it expanded greatly with the appearance of the primates, especially, human beings. The frontal cortex, for example, allows us to have ideas and to develop mindsight maps that give us insight into our inner worlds. It allows us to create representations of time, a sense of self, moral judgments, etc. The prefrontal cortex links the brainstem, the limbic area the higher cortex, the body and our natural environment and social world.

The brainstem, which is also called the reptilian brain, was formed hundreds of millions of years ago. Neurons in the brainstem come into play when events require fight-flight-freeze or faint responses, which are responsible for our survival when we are threatened or in danger. However, our brainstem defence strategies – fight, flight, immobilization and shut down, are not voluntary. They occur outside the realm of our conscious awareness since our nervous system is continuously assessing risk and danger in the environment and making fast survival oriented decisions. Humans and other mammals like dogs, monkeys or koalas, only resort to fight or flight when they are able to. If, for instance, they are confined in a cage or strapped down or if fight and flight are evaluated as impossible and futile then the nervous system ‘opts for’ immobilization, passing out and leaving the scene. However, humans do not rely only on these four F responses of brainstem reactivity, but in times of stress they also have the capacity to tend and befriend, which activates our social engagement system that is embedded in our mammalian brain.

Additionally, the brainstem controls energy levels of the body and shapes energy levels of the brain and it receives input from the body and also sends input back down to the body to regulate basic processes, such as, the functioning of the heart, lungs, etc. The heart, the intestines and other major organs have an extensive network of nerves that process complex information and send data to the skull-based brain. For instance, the medulla, which is part of the brainstem, helps transfer neural messages from the brain to the spinal cord. Our immune system also interacts with our nervous system. Finally, the cauliflower shaped cerebellum is important for being able to perform tasks, such as, walking, writing and standing balanced and upright.

Α. Catch Bull at Four is Cat Stevens’ sixth album. The lyrics below are from this album

Sitting

Oh I’m on my way I know I am,
Somewhere not so far from here
All I know is all I feel right now,
I feel the power growing in my hair

Sitting on my own not by myself,
Everybody’s here with me
I don’t need to touch your face lo know,
And I don’t need to use my eyes to see

Oh life is like a maze of doors
And they all open from the side you’re on
Just keep on pushing hard boy, try as you may
You’re going to wind up where you started from
You’re going to wind up where you started from

Β. A while ago I came across Francis Cabrel’s lyrics of La Corrida by chance. Recently I heard it on youtube, sung by Λαυρέντη Μαχαιρίτσα, a Greek singer, and Pilouka Aranguren

Ο Ταύρος (The Bull)

Part of the lyrics in Greek

Ώρες ατέλειωτες περίμενα, σ’ αμπάρι σκοτεινό
Άκουγα γλέντια και τραγούδια στην ορχήστρα
Τρίζει η πόρτα και ξεχύνομαι στο φως ν’ αναδυθώ
Φανφάρες, τύμπανα και θεατές γύρω απ την πίστα
Απ’ την αρχή κατάλαβα πως πρέπει ν’ αμυνθώ
Δεν έχει έξοδο κινδύνου αυτό το μέρος
Κλείσαν τους δρόμους γύρω μου κι εγώ πισωπατώ
Προκλητικός ο χορευτής – θα κλαίει στο τέλος

Ανδαλουσία μου μακρινή, κάκτοι, λιβάδια δροσερά
Δεν θα μασήσω μπρος στον άθλιο σαλτιμπάγκο
Τρέχω ξοπίσω απ’ τα φαντάσματα, ανέμους κυνηγώ
Τα κέρατά μου ακουμπάνε τα πανιά τους
Νιώθω το αίμα που αναβλύζει και το αίμα στον λαιμό
να πέσω θέλουν, να υποταχτώ μπροστά τους
Που ξεφυτρώνουν οι παλιάτσοι; Ποιος τους ρίχνει στην σκηνή;
Κοστούμια χάρτινα παλεύω κι ακροβάτες
Γέρνω στην άμμο την υγρή, Ανδαλουσία μακρινή
Ας σταματούσανε οι μπάντες κι οι παράτες
Ακούω τα γέλια και τα ‘όλε’ τους καθώς ψυχορραγώ
σκοπό μακάβριο χορεύουν οι τορέρος
Ανδαλουσία μου γλυκιά στήνουνε γλέντια τρομερά
Πάνω απ’ το μνήμα μου στο ξένο ετούτο μέρος

Fairy tales and symbols

Unpacking ‘Let me be’Scan180final‘Deeper meaning lies in the fairy tales of my childhood
than in the truth that life teaches’
(Friedrich von Schiller, 1759-1805)

Sigmund Freud and other more recent psychoanalysts, psychologists, writers, artists, etc, have explored fairy tales and myths in an effort to understand psychological processes and defence mechanisms, like splitting, projection, idealization and denial, developmental stages, trauma, and family and other group dynamics because they believe/d that through exploration and analysis of these narratives one can increase insight and self-awareness, and ultimately, transform painful experiences. Fairy tales like dreams may offer a window into our unconscious material or implicit memories and may reveal a lot both about the author of the story, as well as, the reader. Furthermore, fairy tales and myths reflect and shed light on particular cultural contexts and the morality and politics of the era they were created. They often depict and explore family dynamics, conflict and ways of coping in difficult situations, and contain moral lessons and empowering endings where the victimized and small triumph over the cruel and powerful and where homeostasis and equilibrium of the system-group is eventually restored. Religious themes, practices and moral lessons are also common themes, and one such example is the rather sad story of Karen, the young orphan girl, in the Red Shoes. Central themes in many fairy tales and myths are human tendencies, traits and behaviours like lust for power and wealth, courage and self-sacrifice, cruelty and stupidity, kindness and fairness. Symbolism is used to express themes, aspects of personality, emotions and group dynamics and it is very interesting how common symbols linked to similar psychological processes, experiences, group dynamics or moral lessons are found across cultures and civilizations. For instance, fruit, mirrors, forests and trees, animals and other objects appear in many stories. In Snow White it is the poisonous apple that sends her into a comma or state of dissociation. It is the apple that keeps her in this state of temporary death, until she is able to spit it out. ‘And it happened that they stumbled over a tree-stump and with the shock the poisonous piece of apple which Snow White had bitten off came out of her throat. And before long she opened her eyes, lifted up the lid of the glass coffin, sat up, and was once more alive’ (Snow White – written by the Grimm Brothers and translated into English by Margaret Hunt). In this same story another common fairy tale symbol, the all-seeing mirror, reflects Snow White’s inability to escape her cruel step-mother’s watchful eye. The mirror is the very tool that allows her step-mother to be aware of every step she takes, and thus, to continually hunt her down, jeopardizing her attempts to remain safe.

Often the characters in these stories have had difficult childhoods in their family or have been mistreated, abused, rejected, neglected and manipulated by absent fathers, cruel step-mothers or envious and competitive siblings. Two very popular fairy tales of familial mistreatment are Snow White, the heroine of a popular German fairy tale originally published by the Grimm Brothers in 1812, and the hundreds of variants found all around the world of the story of Cinderella, which is believed to have been originally recorded in China, then retold by Glambattista Basile in Italy, by the French Charles Perrault in 1697, by the Grimm Brothers in 1812, and so on. Another perhaps less known story of parental betrayal is the story The Girl without Hands collected by the Grimm Brothers. Again there are several versions of this story as well. The heroes or heroines are often forced to leave the family or land where their victimization took place in search of love, safety and a better life. The journey, which often contains hardships, usually ends in release, transformation and spiritual growth, redemption and happiness.

More recently, Bruno Bettelheim, who has published Uses of Enchantment: The Meaning and Importance of Fairy Tales (1976), incorporates fairy tales into his therapy practice because he believes that fairy tales are an important tool for children learning to understand cultural reality and make their way in the world. Fairy tales viewed as allegories and adapted to suit the age of the reader, for some are high too violent for young children, can be useful tools for people to explore their own experiences and work out resolutions. An image or theme may resonate with an unconscious process in the reader and it can generate strong emotions, like fear, anger or sadness, which can then lead to processing and positive cognitive reframing. Also, because heroes and heroines escape destructive forces and overcome injustices and cruelty, many fairy tales contain powerful images and messages of transformation and healing. In any case, because the capacity of adaptation and transformation is not only dependent on our environment, but also lies within us, stories and our own meaning making of them may assist us in finding our way and in healing our wounds. According to Joseph Campbell, many of the world’s most important myths support people’s path towards fulfilment, which he calls bliss.
