1. Backward journey of a neuron
Neurons are specialized cells, and their effective communication is vital to the proper functioning of the peripheral and central nervous system. In this part, we shall cover the backward journey of transmission. Neurons transmit electrical information through the body. The process of transmission should flow well, but there exists a gap between one neuron and the next one called the synaptic junction. The gap is known as the synaptic cleft. Since the electrical signal cannot move over this cleft, it has to be converted into a chemical message called the neurotransmitter. The chemical message moves to the other neuron where the message is reverted into an electrical signal, and the transmission process goes on. …show more content…
The neurotransmitters are from the axon and travel across the synapse. After relaying information, the neurotransmitters revert into the axon by the neurotransmitter reuptake. The reuptake is to protect them from destruction to ensure their reuse whenever necessary. If there were no reuptake, the neurotransmitters would risk exposure to enzymes that degrade or destroy them.
Thalamus: Thalamus is the gray matter in the brain between the midbrain and the cerebral cortex. If the thalamus is damaged might result in the loss or partial loss of any or all of those sensations.
Corpus Callosum: It allows the exchange of information between the two spheres of our brain. If we did not have it, the two spheres of our brain would be unable to transmit information to each other hence no communication would occur.
Wernicke’s area: It is part of the cerebral cortex concerned with speech. .If it is damaged, we get Wernicke’s aphasia in which speech is fluent but does not make sense. The person uses the wrong words.
Neuroplasticity: It gives the brain the capability of forming new neural connections especially after illnesses. If we did not have them, our brains would be unable to adjust to new situations that occur during illnesses and …show more content…
It becomes unbearable as a parent with a sick child. The body becomes stresses watching the child’s pain. However, when one realizes the dangers of falling ill too due to the self-inflicted stress, he relaxes to reduce the probability. Upon relaxation, the body returns to its normal functioning mode.
4. Methods that psychologists use to learn about the functions of the brain PET Scans
PET scans use a radioactive sugar injected into the bloodstream to track the activity of brain cells, which is enhanced and color-coded by a computer. SPECT allows for the imaging of brain blood flow.
Neuroimaging method
Psychologists employ this approach to animals. They place detectors in the brain of the animal. They then record analysis of different reactions to different electrical activities. Through this method, we learn that feature detector that detects movements, faces, and even sounds. ERPs allow researchers to look at the timing and progression of cognitive processes. The brain is seen through a computer screen.
