Study Notes

Neurons and Glial Cells

Neurons function as interconnected information processors within the nervous system.
Glial cells support neurons through insulation, communication, and transportation of nutrients and wastes.

Forebrain Overview

Comprises nearly half of the brain's total mass.
Divided into four major lobes: Frontal, Temporal, Parietal, and Occipital.

Cerebrum Functions

The largest part of the forebrain.
Thalamus: Serves as the central relay for all senses except smell.
Hypothalamus: Interfaces between nervous and endocrine systems; regulates emotions such as aggression, hunger, thirst, and sexual behavior.

Limbic System Components

Amygdala: Central to emotion experience and memory association; damage can lead to apathy.
Hippocampus: Key to learning and memory; damage can result in Alzheimer’s or amnesia.

Frontal Lobe Functions

Located at the front; responsible for decision-making.
Broca’s area: Involved in language production.
Motor cortex: Coordinates movement planning.
Prefrontal cortex: Engages in higher-level cognitive functions like critical thinking.

Temporal Lobe Functions

Positioned behind the temples; associated with memory and emotion.
Auditory cortex: Handles auditory information processing.
Wernicke’s area: Facilitates language comprehension.

Parietal Lobe Functions

Located at the top; maintains spatial relationships on the somatosensory cortex.
Somatosensory cortex: Processes sensory information.

Occipital Lobe Functions

Found at the back; organizes visually in a retinotopic manner.
Primary visual cortex: Responsible for processing and interpreting visual information.

Midbrain Characteristics

The smallest brain region; plays a role in pain perception.
Substantia nigra: Contains dopamine-producing cells critical for movement.
Reticular formation: Regulates circadian rhythms, arousal, alertness, and motor activities; damage can cause comatose states.

Hindbrain Overview

Located at the lower brain region; includes the Medulla, Pons, and Cerebellum.

Medulla Functions

Controls autonomic processes like breathing and blood pressure regulation.
Also regulates salivation and chewing.

Pons Functions

Acts as a connector between the brain and spinal cord, essential for information relay.

Cerebellum Functions

Known as the "little brain"; responsible for balance, coordination, and fine motor skills.
Damage can lead to ataxia, characterized by loss of balance and control over muscles.
