Physiological Psychology and Psychopharmacology Lecture: Part Two

Flashcards covering key terms and concepts from part two of the physiological psychology and psychopharmacology lecture.

Hypothalamus

Regulates homeostasis by influencing body temperature, appetite, blood pressure, and hormonal responses.

Suprachiasmatic nucleus

Biological clock located in the hypothalamus that regulates circadian rhythms.

Thalamus

Relay station for sensory information, transmitting it to the appropriate areas of the cortex.

Korsakoff syndrome

A condition caused by thiamine deficiency leading to memory disturbances such as anterograde amnesia.

Basal ganglia

Structures involved in coordination of voluntary movement, procedural memory, and emotional responses.

Limbic system

Group of structures involved in emotion, motivation, and memory, including the amygdala and hippocampus.

Amygdala

Brain structure that processes emotions, particularly fear and aggression, and attaches emotions to memories.

Hippocampus

Involved in the consolidation of declarative memories and spatial memory.

Frontal lobe

Part of the cerebral cortex involved in executive functions such as planning, decision-making, and impulse control.

Broca's area

Region in the left frontal lobe responsible for speech production and language processing.

Wernicke's area

Area in the dominant hemisphere involved in the comprehension of written and spoken language.

Conduction aphasia

A communication disorder characterized by fluent speech with errors and impaired repetition due to damage to the arcuate fasciculus.

Corpus callosum

Major bundle of nerve fibers connecting the left and right cerebral hemispheres.

Neuroimaging

Techniques used to visualize the structure and function of the brain, including MRI and CT scans.

Functional MRI (fMRI)

Neuroimaging technique that measures brain activity by detecting changes in blood flow.

Visual cortex

Area in the occipital lobe that processes visual information; damage can cause visual agnosia.
