Study Notes
Biological Psychology
- Brain: Regulates change from inspiration to expiration. The cerebellum is a convoluted structure on the brain stem's dorsal surface, an important sensorimotor structure. Damage can impair precise movement control.
Myelencephalon
- Also known as the medulla oblongata, the posterior division of the brain.
- Composed of tracts for signals between the rest of the brain and the body.
- Contains the reticular formation (a complex network of 100+ nuclei), involved in sleep, attention and basic life functions including muscle tone, cardio-respiratory regulation, etc., sometimes called the reticular activating system. It extends from the posterior boundary of the myelencephalon to the anterior boundary of the midbrain.
Mesencephalon
- The tectum (or corpora quadrigemina) is the roof of the midbrain and includes the inferior colliculi (auditory function) and the superior colliculi (visual function).
- The tegmentum is on the floor and has the periaqueductal gray (pain and defensive behaviors), substantia nigra (reward, addiction, motor movement), and the red nucleus (motor coordination).
Diencephalon
-
Includes the thalamus, subthalamus, hypothalamus, epithalamus, and pituitary.
-
Thalamus: Large, two-lobed structure acting as the final relay center for both sensory and motor signals to the cerebral cortex. It also plays roles in sleep, consciousness, alertness.
-
Subthalamus: A small, lens-shaped nucleus in the forebrain, involved in basal ganglia functioning.
-
Hypothalamus: Almond-shaped structure, regulates various functions including emotions, motivations, and behaviors.
Metencephalon
- Includes the pons which connects the two hemispheres and contains a respiratory center.
- Also contains the cerebellum, important for sensorimotor functions.
Telencephalon
- The largest part of the human brain, responsible for complex functions like voluntary movement, sensory input interpretation, learning, speaking, problem-solving, etc.
- Composed of the cerebral cortex, limbic system, and basal ganglia.
- Divided into four lobes: frontal (executive functions), parietal (visuospatial processing), temporal (auditory perception and semantics), and occipital (visual processing).
- The Limbic System has the amygdala (emotional associations) and the hippocampus (long-term memory).
Other Information:
- Meninges: Three membranes (dura mater, arachnoid, pia mater) covering the brain and spinal cord.
- Meningiomas: Tumors of the meninges, usually benign.
- Hematomas: Collections of blood outside of blood vessels, with epidural, subdural, and subarachnoid varieties.
- Cerebrospinal Fluid (CSF): Supports and cushions the brain and is produced by choroid plexuses in the brain's ventricles.
