APP 1012 Chapter Notes - Chapter 10: Cingulate Cortex, Medial Longitudinal Fissure, Central Nervous System
Neuropsychology
Neuropsychology is the study of brain-behaviour relationships.
Neurons
Sensory: Carry sensory information from the sensory receptors to the Central Nervous System.
Motor: Transmit commands from the brain to the glands and muscles of the body.
Interneurons: Connect neurons with one another.
Synapses
Synapse is the point at which one neuron communicates with/signals to another. Action potential
travels down the axon transmitting information.
Pre-Synaptic: Neuron sending an impulse.
Post-Synaptic: Call receiving the impulse is the post- synaptic neuron.
Neurons and Neurotransmitters
Resting potential: At rest, a neuron is polarised with a negative charge inside the cell membrane and
a positive charge outside.
Graded potentials: When a neuron is stimulated by another, its cell membrane us depolarised or
hyperpolarized.
Action Potential: If the cell reaches firing threshold, the neuron will fire.
Brain Hemispheres
Two hemispheres separated by longitudinal fissure, connected by corpus collosum. A collection of
axons forming white matter, grey matter composed of cell bodies.

Post-synaptic: call receiving the impulse is the post- synaptic neuron. Resting potential: at rest, a neuron is polarised with a negative charge inside the cell membrane and a positive charge outside.

Two hemispheres separated by longitudinal fissure, connected by corpus collosum. A collection of axons forming white matter, grey matter composed of cell bodies. Limbic system is a network of structures located in the cerebral hemispheres at junction of cortex and subcortical regions.
