Mind and body dualism
What is the difference between the mind and brain
Advantages of classifications in health
Facilitate reporting and inform public health issues such as allocation of resources
•Facilitate meaningful communication and debate between patients, professionals, organisations and legislators
•Promote a feeling of being understood (“we’ve seen this before – your problems are not unique”)
•Provide a framework for research
•Offer evidence for treatment options and some information about natural history and prognosis
Disadvantages of classifications in health
Improved scientific understanding makes a mockery of previous attempts to classify (e.g. phrenology)
•Categorisation means defining thresholds which are arbitrary
•depression / dysthymia / fed up
•obese / well built / chubby / slender
•Categorisation can lead to stigma and prejudice
•Economy of thought may lead to oversimplification, reductionism and ultimately inhumane action
What is used to classify mental disorders
ICD 10
Role of emotion
Motivator for learning
Means of best obtaining rewards/avoiding punishment = stimulus-reinforcer association and instrumental (action-outcome) learning
Emotion
A strong feeling deriving from one’s circumstances, mood or relationship with others
Movement and emotion
Ability or inability to act determines which cluster of emotions is felt
Theories of emotion
Basic
Appraisal
Psychological constructionist
Bayesian model
Theories of emotion: appraisal
Meaningful interpretation of an object/situation by individual
Action readiness
May be automatic
Theories of emotion: psychological constructionist
Psychical compounds of basic ingredients (affect + ideational component)
Internal state subject of meaning analysis
Theories of emotion: basic
Biologically privileged emotion automatically triggered by objects/events
Hard-wired circuits
Variability: cultural ‘display rules’
Models of emotional categorisation
Discrete
Dimensional (valence and arousal)
Componential
Eckman’s 6 basic emotions
Anger
Disgust
Fear
Joy
Sadness
Surprise
Orbitofrontal cortex- appraisal
Input - ventral cortical streams (identity)
Orbitofrontal cortex: medial -reward
Activation: subjective pleasantness
Orbitofrontal cortex: lateral - punishment/ non-reward
Negative reward predictions error
Expectation of punishment
Mesolimbic pathway
Important in reward/behaviour responses
Connected to amygdala and orbitofrontal cortex
Ventral tegmental area
Amygdala- appraisal
Conditioned responses to stimuli predicting harm
Facial expression recognition
Slower response in reversal learning tasks
Little involved in subjective emotional experience
Identification of emotions
Sight- V1, V2, V4, inferior temporal visual cortex
Taste- nucleus of the solitary tract, thalamus, insular taste cortex
Smell- olfactory bulb
Touch- thalamus VPL, somatosensory cortex and insula
Auditory- temporal auditory cortex
Appraisal of emotions
Amygdala
Orbitofrontal cortex
Regulation of emotions
Cognitive and attentional top-down bias
Dorsal and ventrolateral frontal lobes
Reactivity of emotions
Cingulate cortex
Striatum/basal ganglia
Lateral hypothalamus, insula
Medial and ventromedial prefrontal cortex
Reactivity: cingulate cortex
Action-outcome learning
Anterior: outcome
Posterior: action
Mid: output to premotor areas
Posterior cingulate cortex inout
Parietal lobes- spatial/action related information
