Study Notes

The Limbic System

The limbic system is responsible for emotions, motivation, learning and memory.
It is located in the cerebrum and is made up of regions responsible for emotional processing, memory, and motivation.

Short-Term Memory

Sensory Memory: This is the preliminary step of short-term memory. It holds sensory information for a brief period of time.
Capacity: The short-term memory can usually hold around 7 items at a time (plus or minus 2 items).
Location: While a definitive location for short-term memory is debated, it is often associated with structures like the hippocampus and prefrontal cortex.

Long-Term Memory

Capacity: The long-term memory has an unlimited capacity, meaning it can store vast amounts of information.
Location: It is stored in various locations, including the cerebral cortex and hippocampus.

Brain Protection

Meninges: These membranes protect the brain. They are made up of three layers: the dura mater, arachnoid mater and pia mater.

Brain Disorders

Alzheimer's Disease: This is a progressive neurodegenerative disease characterized by memory loss, confusion, and other cognitive impairments. It affects the brain's structure and function.
- Symptoms: Memory loss that affects daily life, difficulty with thinking, speaking and understanding language, impaired judgment, confusion with time and place.
Parkinson's Disease: This is a progressive disorder of the nervous system that affects movement. It causes tremors, stiffness, slow movements, and balance issues.
- Symptoms: Tremors, slow movement (bradykinesia), stiffness (rigidity), problems with balance and coordination, postural instability.
Huntington's Disease: This is a hereditary neurological disorder that causes involuntary muscle movements, behavioral changes, and cognitive impairments.
- Symptoms: Involuntary movements (chorea), cognitive decline, issues with gait, speech impairments, behavioral changes like depression, apathy, and anxiety.
