Q

Hebb’s Law & Freud

A
  • Neurons that fire together, wire together
  • Freud did propose this theory 60 years before though - Law of Association
  • Freud said: that patients came up with interesting connections if he did not interfere
  • These were thoughts and feelings usually pushed down

Q

Unconscious and Threat Systems

A
  • Unconscious is activated when threat is experienced
  • Perceived through our 5 senses
  • Could be a gut instinct as well
  • When amygdala triggers fight/flight or freeze actions are largely involuntary

Q

Memory Plasticity

A
  • Freud moved away from the idea that memories are permanent
  • Memories can be changed by subsequent events
  • Memories can be retranscribed
  • To change memories they have to be in our conscious

Q

Transference & Freud

A
  • Social Memory and unconscious
  • Can be made conscious within the therapy process
  • When an individual redirects emotions from one person to another
  • Freud said it was a good thing as it can bring emotions to consciousness

Q

Transference

A
  • Freud found patients would view him as the client
  • Relived experiences rather than remembered them
  • Transference of early trauma could be altered if attention was drawn to the current situation
  • Neural networks and associated memories could be retranscribed

Q

State Dependent Memory

A
  • Depression creates a negative bias for remembering
  • Selective scanning of environment that focuses on the negative
  • Implicit dysfunctional memories can cause us to recreate negative patterns in behaviour
  • This can even occur if the patterns are unsuccessful
  • Our perception of the world is based on past experience

Q

Trauma and Memory

A
  • People who experience trauma in first three years can have little explicit memory of the trauma
  • BUT Implicit memories can be triggered when similar events occur
  • Procedural memories of emotive experience can get repeated in transference or in life

Q

Uncovering Trauma Memories

A
  • Therapist can help people to bring unconscious memory into explicit conscious context
  • This way they are retranscribed into conscious explicit memory

Q

Dream Analysis

A
  • Dreams are related to traumatic memory - nightmares
  • This is reactivated during sleep
  • Brain regions for emotion, sex, survival & aggressive instincts are very active
  • Prefrontal cortex is inhibited
  • In this way dreams can reveal impulses usually blocked from conscious awareness
23
Q

Dream States & Neural Plasticity

A

Sleep affects Neural Plasticity by consolidating learning & memory

We remember better after a good nights sleep

Connected to enhancing emotional memories

Allows hippocampus to turn short term memories to long term memories

24
Q

Laterality & Psychotherapy

A

Left & Right brain integration relies on secure attachments

Also on co-construction of narrative for labelling feelings

Therapy can reintegrate disconnected hemispheres by testing reality

Puts words to feelings within a caring relationship context

25
Q

Therapy & Hippocampus

A
  • People who improve in psychotherapy also find their memories improve
  • This may be due to stimulated neural growth in Hippocampus
  • Hippocampus shrinks with depression
26
Q

Memory 3 broad categories

A
  • Conscious
  • Preconscious
  • Unconscious
27
Q

Conscious Memory

A
  • Remembering the past
  • Content of previous experiences
  • Reports of day-to-day life
28
Q

Preconscious Memory

A
  • Holds memories that don’t need immediate attention
  • Can be easily brought to conscious awareness
29
Q

Unconscious Memory

A
  • Memory unavailable to conscious consideration
  • Can manifest in behaviours, attitudes, feelings
  • Can be more complex - defenses, self-esteem and transference
30
Q

Memory - Role of the therapist

A
  • Identify and Decipher unconscious memory and make it available to the patient
  • Freud said this was the role of the therapist
31
Q

Rebuilding the Brain

A

Increasing interconnection and integration of neural networks between unconscious and conscious memory

32
Q

Resistance to Therapy or Memory Deficit?

A
  • Many psychological disorders result in memory deficit.
  • Involve high rates of cortisol and small hippocampus size
  • Depression leads to vulnerability to negative bias when remembering events
33
Q

State Dependent Memory

A
  • Depression causes scanning of the environment
  • We seek information to reinforce negative bias
  • Patients say if they wake up depressed they feel worse
  • Even if nothing has changed.
34
Q

Multiple Memory Systems

A
  • Two Broad Categeories - Implicit & Explicit
  • Each type of own domains, focus of learning, neural architecture and development timeframe.
  • Developing Hebbian Synapses - fire together wire together
  • Dendrite remodeling and long term potentiation
35
Q

Long Term Potentiation

A
  • Persistent strengthening of synapses
  • Leads to a long-lasting increase in signal transmission between neurons.
  • Important process for synaptic plasticity.
36
Q

Explicit Memory

A
  • Conscious learning of semantic, sensory and motor experiences
  • Some of these lay just below consciousness until they become important
  • Like the tip of an iceberg
37
Q

Implicit Memory

A
  • Visible in patterns of learning stored in hidden layers of nerual processing
  • Mostly not connected to or accessible to the consciousness
  • Can be everything from riding a bike to repressed trauma
  • Like the vast iceberg beneath surface of the water
38
Q

Triune Brain & Memory

A
  • Reptilian Brain has genetic memories controls implicit actions and is non verbal
  • This acts like the Freudian Unconscious
39
Q

Early and Late Memory

A
  • This is implicit memory and explicit memory
  • Called this because this is the order and timing in which they develop
  • Implicit memory begins before birth and combine with body function after birth
40
Q

Childhood Amnesia

A
  • Due to delay of maturation of explicit memory
  • Also as development of hippocampus and cortical structures happens later
  • But we still learn to walk and talk with underdeveloped explicit memory
41
Q

Amygdala Memory Networks

A
  • Central hub of fear processing
  • Located within the limbic system
  • Fully developed by 8 months gestation - We can experience fear in the womb
  • At first we depend on others to moderate fear until we learn to regulate by ourselves
    *
42
Q

Basolateral Amygdala

A
  • Evolves alongside expansion of cerebral cortex
  • Supports ability to assess and appraise the world
43
Q

Appraisal for Danger

A
  • Amygdala Connectivity integrates with the senses - Especially Vision
  • Assesses danger, safety, familiarity and approach-avoidance situations
  • Remains attentive to survival assessment
  • Can create emotional bias by colouring our experiences - fears/sure based biases
    *
44
Q

Two Circuits of Sensory Input to Amygdala

A
  • First travels directly from Thalamus
    • Implicit - allows for fast response survival decisions with minimal sensory input
  • Second loops through cortex and hippocampus then amygdala
    • Adds Cortical Processing to appraise context, inhibition, perception and behaviours
45
Q

Hippocampal Memory Networks

A
  • Sustained stress leads to excessive glucocorticoids in the hippocampus
  • Too much causes dendrite degeneration, cell death
  • Causes vulnerability to neurological problems, and poor hippocampus function
  • Connected to poor memory
46
Q

Amygdala & Hippocampus Relationship

A
  • Contributes to Top-Down and Left-right integration
  • Amygdala does Right-Down - Emotional & somatic organisation of experiences
  • Hippocampus does Left-Top - conscious, logical and cooperative social function
  • This connection supports affect regulation, reality testing, resting states and arousal anxiety
47
Q

Opposites of Amygdala & Hippocampus

A
  • Amygdala heightens awareness of specific attention, can generalise
  • Hippocampus inhibits responses, attention and habituation, involved with discrimination
48
Q

Flashbacks & Amygdala

A
  • Flashbacks are multi-sensory
  • Often experienced as if they are happening in real time
  • Stereotyped and repetitive so possibly not connected to the hippocampus
49
Q

Prozac & Paxil

A

May be effective in treating depression because the boost hippocampus

Also helps moderate amygdala action

50
Q

Memory is Malleable

A
  • False memories occur suggesting that episodic memories are less reliable
  • Most therapists are aware of false memories and care needed to minimise this experience
  • False memories can be planted and seem very real
51
Q

Explanatory Coherence

A
  • When the memory is distorted by: -
    • A need to provide an explanation
    • Can assimilate it when explaining other propositions
    • Can offer analogous explanations.
52
Q

Nachtraglichkeit

A
  • Provides the memory, not the event with traumatic significance
  • Means a circular complementarity of both directions of time
  • Reconceptualise a memory based on evolving maturity
  • An Idea developed by Freud
  • Memory is evolving and can be influenced for the positive
