Key Principles of Assesing cognitive function
|
Orientation (Time, Space, Person)
Attention and Concentration Memory (Long and Short term) Visual cognition General Intelligence Replicate motor commands |
|
|
Specialised Tests of Cognitive Function
|
Rey Figure (Frontal lobe defects)
Brain Imaging (eg PET Scan) Angiography EEG/MEG |
|
|
Effects of Brain Damage on Cognitive Function
|
General Deterioration in brain function (eg alcohol)
Differential effects, depending on location, extent and type of damage (eg frontal lobe syndrome) Highly specific effects in certain locations. |
|
|
Orbitofrontal Syndrome
|
Disinbited
Impulsive Behaviour Inapproriate Affect Poor judgement and insight Distractability |
|
|
Frontal Convexity Syndrome
|
Apathetic
Indifference Psychomotor retardation Motor Perseveration and impersistance |
|
|
Medial Frontal Syndrome
|
Akinetic
Lack of spontaneous movement sparse verbal output lower extremity weakness and loss of sensation |
|
|
Object Recognition
|
Ventral Visual Stream
Inferotemporal (IT) Cortex. subgroups of neurons are very selective for: faces highly experienced objects. these neurons can be view dependent. |
|
|
Prosopagnosia
|
Inability to recognise faces (lower temporal lobe damage)
Posterior Cerebral artery damage. |
|
|
Phonagnosia
|
inability to recognise voices (upper temporal lobe damage)
|
|
|
Declarative Memory
|
Explicit
Records Facts and Events Accessible to consciousness Medial Temporal Lobe; diencephalon |
|
|
Procedural
|
Implicit
Skills and behaviours motor response + sensory input not conscious, difficult to forget Procedural (striatum) Classic conditioning= cerebellum and amygdala |
|
|
Short-term memory
|
Working memory
Temporary storage area, limited in capacity requires continuous rehearsal exists in multiple brain areas |
|
|
Long-term memory (LTM)
|
Greater capacity, more permanent
Does not require continuous rehearsal |
