Lecture 5September 24
Neurons
Understand neurons, neurotransmitters, and neuroanatomy for test.
The private life of the brain 2000. Susan Greenfield
Brain=mind, in most cases. The mind also exists outside of the person.
Psychologists have not yet solved the mind-body problem.
One ant is no ant. A million ants is a viable community of organisms that
exhibits coordinated, self-directed behaviour.
One neuron is no neuron. 100 billion neurons are you.
How do our subjective experiences go from neurons to me?
Three Types of Neurons
1.Sensory (Afferent) Neurons (body to brain)
2.Motor (Efferent) Neurons (brain to body)
3. Interneurons (thinking, reasoning, communicate amongst themselves)
Dendrites: receive information from other neurons and transmit towards the cell
body.
Cell body: keeps the neuron alive and determines whether it will fire. (Transmit)
Axon: extending fiber that conducts impulses away from the cell body
Myelin Sheath: fatty insulation that may surround the neurons axon (speeds up
transmission, and reducing the resistance)
Myelin: prevents signals in adjacent cells from interfering with each other. It
speeds up the conduction of neural impulses, allowing for the speed of
transmission required for perception, motor control, etc…
Terminal Buttons (or axon terminals): receive the action potential from the axon
and are involved in transmitting that info on to other neurons through release of
neurotransmitters.

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
