The Behaving Brain: Video Response
The video put the chapter into visual perspective for me in terms of learning about our brain structure and it’s different parts. The video describes the three important jobs our neurons do: receive information from other cells, process information, and transmit it to the rest of the body. Without our neurons we would have no brain activity. All behavior begins with an action from a neuron. First the brain gathers information from the receptors and spread it around it’s branch fibers, or dendrites. Next the information is sent to the soma, the neurons cell body, where it is combined with other information. Finally, the entire input is passed along within the axon in form of nerve impulses. It’s fascinating to learn that no neurons actually ever touch; they send messages across the synaptic gap, called neurotransmitters. Nerve impulses and transitive chemicals give our human behavior its complexity psychologists and scientists have been studying for ages. Our brain regulates our metabolism, temperature, respiration, and allows us to learn, remember, and decide. The brain uses all it’s parts reacting as a complete part of the nervous system. The brain stem connects the brain to the nerves and spinal cord and is the center for basic life support –breathing, beating of the heart, walking, and sleeping. The cerebellum controls our poster and body movement. Conclusively the limbic system balances our temperature, blood pressure, emotions, and sexual desire. We would not be able to complete these necessary unconscious tasks without the amygdala, hippocampus, hypothalamus, and the thalamus. Our cerebrum is the largest part of our brains. This is where our nerve impulses are translated into words and ideas. The outer layer of the cerebrum is the cortex, the center of thought, perception, and the integration of all responses and sensation. Without the video I honestly don’t think I would’ve been able to explain ANY of the brain...
