Study Notes

The Human Brain: Anatomy and Function

The hypothalamic thermostat regulates body temperature and activates mechanisms accordingly
The cerebrum is the largest part of the human brain and is responsible for sensory perception, memory, thought, and voluntary motor actions
The cerebral white matter is composed of glia and myelinated nerve fibers that transmit signals through three types of tracts
The limbic system is an important center of emotion and learning, with prominent components including the cingulate gyrus, hippocampus, and amygdala
The basal nuclei, including the caudate nucleus, putamen, and globus pallidus, are involved in motor control
Processing cognition involves widely distributed association areas of the cerebral cortex, which make up about 75% of all brain tissue
Memory involves learning, storage, and retrieval processes and is managed by brain structures such as the hippocampus, cerebellum, and amygdala
Emotional feelings and memories involve interactions between the prefrontal cortex, diencephalon, hypothalamus, and amygdala
Sensation is processed by primary sensory cortex and association areas, with special senses like vision, hearing, equilibrium, taste, and smell each having dedicated cortical regions
Motor control is regulated by the primary motor cortex, precentral gyrus, upper motor neurons, basal nuclei, and cerebellum
Different brain regions are responsible for components of language, such as reading, writing, speaking, and understanding words
Cerebral lateralization, the difference in structure and function between the two cerebral hemispheres, is correlated with handedness, age, and sex, with the left hemisphere usually the categorical hemisphere and the right hemisphere the representational hemisphere.
