He is a Licensed Clinical Social Worker in the states Read More Science has made huge strides in understanding the human brain and how it functions.
Anatomy of the Brain There are different ways of dividing the brain anatomically into regions. The forebrain or prosencephalon is made up of our incredible cerebrum, thalamus, hypothalamus and pineal gland among other features.
Neuroanatomists call the cerebral area the telencephalon and use the term diencephalon or interbrain to refer to the area where our thalamus, hypothalamus and pineal gland reside.
The midbrain or mesencephalonlocated near the very center of the brain between the interbrain and the hindbrain, is composed of a portion of the brainstem. The hindbrain or rhombencephalon consists of the remaining brainstem as well as our cerebellum and pons.
Neuroanatomists have a word to describe the brainstem sub-region of our hindbrain, calling it the myelencephalon, while they use the word metencephalon in reference to our cerebellum and pons collectively.
Histology Brain cells can be broken into two groups: Neurons, or nerve cells, are the cells that perform all of the communication and processing within the brain. Sensory neurons entering the brain from the peripheral nervous system deliver information about the condition of the body and its surroundings.
Interneurons send signals to motor neurons, which carry signals to muscles and glands. Neuroglia, or glial cells, act as the helper cells of the brain; they support and protect the neurons.
Psychologists study the brain and the nervous system because these parts of the body are essential to the way that people behave, think and feel. Psychology is the scientific study of people's behavior and their mind so studying the brain and nervous system is always going to be a crucial element. This session explores how the brain's structure relates to specific mental functions. The cases of some famous patients, such as Phineas Gage and Patient H.M., demonstrate key points about the brain basis of personality and memory. Physiological psychology is the study of the physiological basis of how we think, connecting the physical operation of the brain with what we actually say and do. It is thus concerned with brain cells, brain structures and components, brain chemistry, and how all this leads to speech and action.
In the brain there are four types of glial cells: Astrocytes protect neurons by filtering nutrients out of the blood and preventing chemicals and pathogens from leaving the capillaries of the brain. Oligodendrocytes wrap the axons of neurons in the brain to produce the insulation known as myelin.
Myelinated axons transmit nerve signals much faster than unmyelinated axons, so oligodendrocytes accelerate the communication speed of the brain.
Microglia act much like white blood cells by attacking and destroying pathogens that invade the brain. Ependymal cells line the capillaries of the choroid plexuses and filter blood plasma to produce cerebrospinal fluid. The tissue of the brain can be broken down into two major classes: Gray matter is made of mostly unmyelinated neurons, most of which are interneurons.
The gray matter regions are the areas of nerve connections and processing. White matter is made of mostly myelinated neurons that connect the regions of gray matter to each other and to the rest of the body. Myelinated neurons transmit nerve signals much faster than unmyelinated axons do.Neuroscience is the place where psychology meets biology to further our understanding of physical, psychological, and neurological health conditions, such as the brain’s role in how we perceive.
The Brain Science That Could Help Explain Sexual Harassment How power changes the way people process their worlds, in ways that explain not only corporate greed or erratic executive behavior, but. One of the most complex systems known to us today, the brain is made of systems and parts that all work together to keep the human body functioning.
The nervous system, the core of all processes, has two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is.
In this activity you will explore the human brain, the key element of the nervous system. You will learn about its main areas and their functions in regulating everyday life. Understanding the brain's role in all manner of human activity is a central topic in psychology.
