Study Notes
The Brain
- Comprised of three main parts: Brain Stem, Cerebellum, and Cerebrum
- Cerebrum is divided into four lobes: Frontal, Parietal, Temporal, and Occipital
Brain Stem
- Reticular: regulates sleep and wakefulness
- Periphery Sensory: connects sensory organs from the environment; signals go through thalamus and appropriate cortical areas
- Autonomic Sensory: responsible for perception of sensations
- Periphery Reward: regulates memory and behavior; connects to nucleus accumbens, ventral tegmental area, amygdala, and frontal cortex
- Limbic: regulates emotions; communicates with nucleus accumbens and frontal cortex to strengthen drug-seeking behavior
- Learning: responsible for learning and memory formation; connects sensory organs to thalamus, hippocampus, and finally frontal cortex
Cerebellum
- Controls coordination and balance
- Involved in emotion, motivation, and memory formation
Cerebrum Lobes
Frontal Lobe
- Controls movement, attention, short-term memory, planning, and speech
Parietal Lobe
- Processes information including touch, spatial awareness, and sensory inputs
Temporal Lobe
- Decodes sensory inputs, including visual and auditory information
- Involved in memory formation and language comprehension
Occipital Lobe
- Primarily responsible for processing visual information
The Meninges
- Three layers of tissue that protect the brain and spinal cord: Dura Mater, Arachnoid, and Pia Mater
Meninges Functions
- Dura Mater: provides support for blood vessels and delivers blood to the CNS
- Arachnoid: allows for the exchange of nutrients and waste
- Pia Mater: supplies the cerebral and spinal cord with oxygen and nutrients
- Pia Mater also contains cerebrospinal fluid, which protects the spinal cord
Neuron Anatomy
- Dendrites: receive information
- Nucleus/Soma: where DNA is made
- Axone: sends signals
- Myelon Sheath: insulates axon, allowing for faster signal transmission
- Axon Terminals: sends signals to other neurons
