Chapter 2 2.3 Flashcards
Substantia nigra & its connections to striatum
When the substantia nigra is electrically stimulated, no movement occurs.
Midbrain
A small structure between the hindbrain and forebrain that relays information from the eyes, ears, and skin and hat controls certain types of automatic behaviors.
Forebrain
The brain’s most highly developed part is responsible for the most complex aspects of behavior and mental life.
Thalamus
A forebrain structure that relays signals from most sense organs to higher levels in the brain and plays a vital role in processing and making sense of this information.
Hypothalamus
A structure in the forebrain that regulates hunger, thirst, and sex drive.
SCN - suprachiasmatic nuclei
A bilateral structure located in the anterior part of the hypothalamus.
Limbic system amygadala
A structure in the forebrain that, among other things, associates features of stimuli involved in memory and emotion.
Hippocampus
A structure in the forebrain is associated with the formation of new memories.
Visual brain
The primary cortical region of the brain that receives, integrates, and processes visual information relayed from the retinas.
Meninges - hemisphere,
The three membraneous layers provide a protective brain and spinal cord cover.
Cerebral cortex & lobes
The outer surface of the brain
Corpus callosum
A massive bundle of axons connects the right and left cerebral hemispheres and allows them to communicate with each other.
Frontal lobes
The front part of the brain
Prefrontal lobes
The gray matter of the anterior part of the frontal lobe is highly developed in humans and plays a role in the regulation of complex cognitive, emotional, and behavioral functions.
Manipulating Genes - Alzhimer’s disease
Progressive mental deterioration can occur in middle or old age.
