- Cognitive Neuroscience
- History
- Localisation view (phrenology, Broca + Wernicke)+ aggregate field theory
- Neuron Doctrine
- Empiricism + Behaviourism (Watson + Skinner)
- Methods
- Cognitive Psychology,(mental ops, info from environment(, Cognitive Neuroscience(metal ops + specific brain areas/neural interactions etc)
- Posner-representations/reaction times + stimulus onset asynchrony
- Sternberg-memory task, stroop task
- Experimental techniques-Animal research. (single cell recordings, genetic manipulations). Neurology (cognitive dysfunction, trauma,,stroke,tumors, neuruodegeneative disease, infectious disorders, epilepsy), Functional neurosurgery (DBS), Brain lesions (single vs double dissociations, Group vs individual studies), Non -invasively (FMRI, PET), virtual lesions (TMS),
- Learning + Memory
- 1)encoding 2)storage 3)retrieval
- Sensory memory, STM (KF, left temporoparietal junction), Working memory (central executive), LTM (declarative, Non-declarative, perceptual learning)
- encoding + retrieval- frontal cortex. Left- semantic retrieval + episodic encoding. encoding of words. right-episodic retrieval. faces encoded. (hemispheric specialisation).
- H.M , hippocampus lesion (CA1) (anterograde episodic amnesia)
- FMRI- items LTM stored where encoded,
- Memory consolidation,(fast=MTL + HIPPO, slow= cortical assocation areas), MTL- relecant - LT episodic not semantic
- Synaptic transmission, receptor types, Glutamate as neurotransmitter, long term potentiation, Morris Water maze
- serial reaction time (test implicit + procedural learning in MTL amnesia), MTL damage still perceptual prime,
- Associative agnosia + apperceptive agnosia. semantic knowledge stored different places
- Attention + Consciousness
- ERP (dichotic listening task, N1 amp larger for attended stimuli. -90ms after stimulus onset. early selection-corticol level.
- Valid-invalid cueing paradigm,
- Overt + Covert. voluntary (top-down, endogenous), involuntary (bottom-up, exogenous). Inhibition of return.
- Spatial, feature, object based attention
- Visual search, pop-out search, conjunction search,
- biased competition model of attention, V1, V2, VP, V4, TEO. V5/MT- movement, V4-colour + shape.
- Source areas, Site areas.
- premotor theory of attention
- unilateral spatial neglect + extinction. representational model. attentional bias model.spatial neglect. object neglect.
- premotor theory of attention
- ERP (dichotic listening task, N1 amp larger for attended stimuli. -90ms after stimulus onset. early selection-corticol level.
- emotion
- S.M,- fear. amygdala
- Ekman + Friesan universal emotions
- Circuit model of emotions. Papez circuit, limbic system.
- Kluver-Bucy syndrome (psychic blindness)
- implicit emotional learning/conditioning
- James-Lange theory + Cannan Bard theory- centre periphernery debate
- implicit- amygdala, explicit- hippocampus.
- James-Lange theory + Cannan Bard theory- centre periphernery debate
- Circuit model of emotions. Papez circuit, limbic system.
- anxious apprension _ anxious arousal
- Cognitive control
- goal oritented behaviour.
- Working memory
- Dynamic filtering
- selective filtering hypothesis
- Dynamic filtering
- Content based approaches. Process based approaches
- inhibition of action
- stop-signal task
- schema control units
- monitoring system
- schema control units
- stop-signal task
- inhibition of action
- preservate
- Wisconsin sorting task
- stroop task
- verb generation task
- stroop task
- Wisconsin sorting task
- Working memory
- goal oritented behaviour.
- Social cognition
- self-referential processing
- resting state network
- self-refrential bias for positive traits
- simulation theory, mirror neurons, empathy
- utilization behaviour
- framing effect
- orbitofrontal cortex
- self-referential processing
- History
