What is the role of the hippocampus?
The hippocampus is essential for converting short-term memories into long-term memories and plays a significant role in spatial memory.
Where is the hippocampus located?
The hippocampus is located under the cerebral cortex within the medial temporal lobe.
What is the function of the amygdala?
The amygdala is involved in processing emotions, especially fear and pleasure, and contributes to decision-making and memory formation.
Where is the amygdala found?
The amygdala is found deep in the medial temporal lobe.
What is the function of the parahippocampal gyrus?
The parahippocampal gyrus is vital for memory retrieval, assisting in recalling previously stored information.
What do the mammillary bodies contribute to?
The mammillary bodies contribute to episodic memory, particularly the recollection of specific events and experiences.
Where are the mammillary bodies located?
The mammillary bodies are located on the ventral surface of the brain near the hypothalamus.
What is the fornix?
The fornix is a major output pathway of the hippocampus that connects it to the mammillary bodies.
What are ascending tracts?
Ascending tracts are sensory pathways that carry sensory information from the body to the brain.
How do ascending tracts function?
Ascending tracts are paired, decussate, and typically involve 2-3 neurons to transmit sensory signals to higher brain centers.
What are descending tracts?
Descending tracts are motor pathways that carry motor commands from the brain to the muscles.
How do descending tracts function?
Descending tracts are paired, decussate, and usually involve two neurons: an upper motor neuron and a lower motor neuron.
