EEG and Brain Function Quiz

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.
