[1][page needed] This field of psychology takes an empirical and practical approach when studying the brain and human behavior.
By studying and gaining knowledge about the mechanisms of the nervous system, physiological psychologists can uncover many truths about human behavior.
[4] Psychologists in this field usually focus their attention to topics such as sleep, emotion, ingestion, senses, reproductive behavior, learning/memory, communication, psychopharmacology, and neurological disorders.
It uses electrical and chemical signals to send out responses to different parts of the body, and it is made up of nerve cells called neurons.
The nervous system is a complex and intricate network of cells and fibers that serves as the communication hub within the human body.
Neurons, the fundamental building blocks of the nervous system, transmit electrical and chemical signals, enabling the rapid exchange of information.
The intricate interplay of the nervous system is essential for maintaining homeostasis, responding to stimuli, and orchestrating complex behaviors and cognitive processes.
Understanding the structure and function of the nervous system is fundamental to comprehending various neurological disorders and advancing medical interventions to support overall human health and well-being.
The body's blood pressure, heart rate, and breathing are generally significantly decreased compared to an alert state.
REM cycles typically occur in 90 minute intervals and increase in length as the amount of sleep in one session progresses.
[18] Sleep is important for the body in order to restore itself from the depletion of energy during wakefulness and allows for recovery since cell division occurs the fastest during the Non-REM cycle.
Sleep is also important for maintaining the functioning of the immune system, as well as helping with the consolidation of information previously learned and experienced into the memory.
Mental stimulation, pain and discomfort, higher/lower than normal environmental temperatures, exercise, light exposure, noise, hunger, and overeating all result in an increase in wakefulness.
Industrial and organizational psychology focuses on the corporate world to help the function of the work flow for organizations and their relationships with employees.
Pharmacology is biomedical science that helps in the branch of research to discover the characteristics of chemicals that affect biological functionalism and the relationship to other parts of the body.
There are programs like company Betterhelp who provide mental health services at discounted rates as well as financial aid that can help reduce costs.
