Psychology
Neurotransmission
Neuron - neurons are in charge of processing and transmitting information using electrical signals (action potentials)
-
-
Axon hillock - the decision maker, functioning as the trigger zone
Axon terminal - the axon terminal is at the end of the axon. The axon terminal transmits signals to other neurons through the synapses
Dendrites - dendrites receive signals from other neurons, and process the information sent from other neurons
Neuroplasticity - the process in which the brain changes due to environment. How our brain adapts based on experiences and the environment
Dendritic branching - when being placed in a new environment or learning a new experience, dendritic branching occurs, creating new connections between neurons
Synapatic pruning - synaptic pruning is the process of the brain removing synaptic connections between neurons. This happens when a connection in the brain has not been used for long periods of time. Synaptic pruning makes functioning synapses more efficient because it does not waste energy on connections that are not used
-
White matter is the myelin sheath protecting axons, and increases when the thickness of the sheath increases
-
Neurotransmitters - chemical messengers that are passed along neurons through the axon, regulating bodily function
Brain imaging
fMRI - functional magnetic resonance imaging. fMRI's are used to map out the function of the brain, measuring brain activity
fMRI's work by detecting the oxygen levels in the brain. fMRI's depend on the BOLD (blood oxygen level dependent. When an area of the brain is active, more oxygen is used. This changes the ratio of oxygenated to unoxygenated hemoglobin, which is then detected by the BOLD imaging
-
The areas of oxygen are different and detected by the fMRI machine because oxygenated blood is less magnetic, via the hydrogen atoms
