For example, stimulating one area of the motor cortex repeatedly and reliably induced hand-to-mouth action (E). They also found sites evoking apparent defensive movements (F) or reach to grasp (G). Each ethologically relevant type of action is organised in zones, and ablations to these zones affect the ability to generate the corresponding ...
- The study of brain activity. A scientist is interested in understanding how the brain operates while someone is reading. This scientist may design an fMRI study and have people complete a specific reading task while in the scanner.
- Lesion studies. Lesion studies were prevalent in early biological psychology and neuroscience. These studies looked for associations between damage or abnormalities in brain tissue and behavior.
- The study of hormones. Biological psychology can concern with how hormones influence behavior. Hormones are chemical messengers that are released by specific glands and travel in the bloodstream.
- Twin Studies. Twin and family studies provide an aggregate estimate of genetic influences on variability in behavioral or psychological outcomes by examining differences between people who share different amounts of DNA.

What does the somatic nervous system do?
The main function of the SNS is to control all voluntary movements. There are receptors in the skin and sense organs (e.g., eyes, mouth, nose, and ears) that can detect changes in the environment, such as temperature, light, pressure, or texture. Once environmental changes have been detected, impulses are created within the sensory neurons, which then carry signals through thespinal nervesto the spinal cord. These signals will then travel up the spinal cord to the brain. The brain will then i...
Reflex Arcs
As well as controlling all voluntary muscular systems of the body, the SNS also processes muscle reflex arcs. Reflex arcs are neural pathways that produce involuntary movements, typically in response to stimuli perceived as imminent danger. This occurs when sensory neurons sense something within the environment and carry this signal directly to the spinal cord, but this is not transmitted to the brain. The spinal cord will instead transmit signals through the motor neurons to the muscles in o...
The SNS consists of two major types of neurons; sensory and motor neurons. These neurons function to transmit signals throughout the body. Neurons contain an axon, which is the longest part of the cell, enabling signals to be transmitted through them. There are also dendrites branching off the neuron soma (cell body) or at the neuron endings, which...
As the SNS is responsible for receiving sensory information and motor movements, symptoms associated with damage to this system include numbness, muscle weakness, and pain. Diabetes is the most common cause of neuropathy in the PNS, but damage can also be the result of autoimmune diseases, infections, and trauma. Damage to the nerves through injury...

Sep 27, 2023 · Motor neurons (also referred to as efferent neurons) are the nerve cells responsible for carrying signals away from the central nervous system towards muscles to cause movement. They release neurotransmitters to trigger responses leading to muscle movement.
Mar 17, 2023 · These actions represent movements usually used by the monkey (ethologically relevant). For example, stimulating one area of the motor cortex repeatedly and reliably induced hand-to-mouth action (E). They also found sites evoking apparent defensive movements (F) or reach to grasp (G).
Aug 1, 2011 · By definition the motor system is the output of the central nervous system and it controls both the somatic system of skeletal muscle for producing behavior, and the visceral system for regulating bodily vital functions.

Central Nervous System. The central nervous system is the main control system of the body. It consists of two parts: the brain and spinal cord. Brain. In addition to obvious functions like thinking, the brain is also responsible for: Perception (i.e. translating information from the senses so it can be understood and processed)
