Study Notes
Brain Structure and Function
- The visual system is hierarchically organised.
- The auditory cortex can be affected in different ways, impacting speech and music perception.
Papez Circuit and Brain Regions
- The Papez circuit includes the hippocampus, but not the caudate nucleus.
- The frontal lobe is responsible for social and emotional behaviour.
- The limbic system works together with the hypothalamus to control emotion and motivation.
Memory and Brain Regions
- Procedural memory is demonstrated by Joe's ability to ride a bike after 27 years.
- The basal ganglia consists of the caudate, putamen, and globus pallidus.
EEG and Sleep Patterns
- EEG was first recorded by Hans Berger.
- The normal EEG frequency range is 0.5-50Hz.
- EEG pattern in REM sleep is characterized by low amplitude, rapid waves.
- Alpha rhythm is replaced by beta waves when people are attentive or thinking hard.
Brain Disorders and Damage
- Damage to the angular gyrus can result in the inability to read, although vision is unaffected.
- Amyloid plaques and neurofibrillary tangles are features of Alzheimer's disease.
- Damage to Wernicke's area can result in comprehension difficulties, while speech and writing remain intact.
EEG Electrode Placement and Wave Patterns
- The letter T in the EEG electrode placement system denotes the temporal lobe.
- The most prominent EEG wave pattern of an awake, relaxed adult with closed eyes is alpha.
- Beta waves are prominent when people are attentive or thinking hard.
Basal Nuclei and Cortex
- The basal nuclei inhibit unwanted muscular activity.
- Convolutions in the cortex are called gyri, and the spaces between them are called fissures.
- The primary motor cortex, premotor area, and supplementary motor area are responsible for maintaining voluntary movement.
