Lecture 16 – neuro intro
Neuroanatomical directions;
- Top of the head = dorsal
- Back = dorsal
- Medial = towards the middle
- Lateral = towards the side
Sections of the brain;
- Horizontal = a slice parallel to the ground
- Frontal (coronal) = slicing bread or salami
- Sagittal = a midsagittal section separates the left and right halves
5 major divisions of the brain;
- Early development of mammalian brain, Pinel (2006). Biopsychology.
- Goes from more basic/automatic areas (hindbrain) to more
complex/cogntive areas (Forebrain).
Myelencephalon = medulla;
- Composed largely of tracts
- Autonomic involuntary functions (breathing, heart rate, coughing
sneezing)
- Origin of the reticular formation – arousal, attention, sleep, more
unconscious aspects of psychological function? Selective attention?
- Coma/chronic fatigue syndrome
Metencephalon;
- Many tracts
- Pons – breathing and interactions with the medulla
- Cerebellum – coordination. Proprioception, inner ear links.
- Sensory motor control/some aspects of cognition?
Mesencephalon;
- Tectum (dorsal surface)
- Inferior colliculi – audition
- Superior colliculi - vision
- Tegmentum (ventral)
- Substantia nigra – sensorimotor
- Red nucleus– sensorimotor
Diencephalon;
- Thalamus – sensory relay nuclei
- Hypothalamus
- Regulation of motivated behaviors
- Controls hormone release by the pituitary
- basic functions of growth, metabolism, and reproduction
- Linking endocrine to CNS
Telencephalon;
- Cerebral cortex
- Limbic system
- Basal ganglia
