PSYC 101 Lecture Notes - Neurotransmitter, Resting Potential, Myelin
Document Summary
Neurons nerve cell; basic building block of the nervous system; transmit information neurons move information neurons connect ideas. Types of neurons sensory neurons motor neurons interneurons. Structures of a neuron cell body contains cell"s nucleus https://www. remnote. com/w/63926081f5fdbf2cb21b71d6/the-neuron-vn2jkwyps7bgi4pnp. Resting potential ions charged elements in and outside of the neuron difference between neural charge outside and inside the neuron: -70 millivolts before neuron fires: resting potential charge difference kept in place by gates. Depolarization a chemical reaction occurs in the neuron which opens the gate positive ions flow in to establish equilibrium if the difference between in/out reaches -50mv, the neuron fires. Action potential ions which flow in at one place in the neuron change the charge at places down the axon, in turn opening their gates this process of electric travel is called an action potential www. youtube. com/watch?v=yp p6byveje https://www. remnote. com/w/63926081f5fdbf2cb21b71d6/the-neuron-vn2jkwyps7bgi4pnp. Key neurotransmitters dopamine involved in movement, learning, attention, emotion, reward.
