Cerebral hemisphere

The prefrontal cortex is the most anterior region of the frontal lobe. It occupies one-third of the cerebral cortex and is key for executive functions such as problem solving, working memory, and emotional control. It is also crucial in decision making and the expression of personality. The prefrontal cortex is imperative for efficient cognitive functioning; damage can result in severe impairment to skills such as emotional regulation, moral behavior, and empathy. In addition, the prefrontal cortex

of chemoreceptors? They trigger visceral reflexes They are found in carotid bodies They are interoceptors They are classed as nociceptors Identify the type of information that travels along the anterior corticospinal tracts proprioception to the cerebral cortex pain and crude touch sensations visceral motor commands to smooth muscle motor commands to skeletal muscles A mechanoreceptor in the papillary layer of the dermis that responds to fine touch is a Free nerve ending Ruffini corpuscle Root

Epilepsy is defined as "an occasional, an excessive and a disorderly discharge of nervous tissue induced by any process involving the cerebral cortex that pathologically increases the likelihood of depolarization and synchronized firing of groups of neurons” (Hughlings Jackson, 1889). To be classified as a generalized seizure the entire brain needs to be involved. One type of Generalized seizure is the ’grand mal’ seizure or tonic-clonic seizure, which also requires a loss of consciousness, equilibrium

the brain. There are two main hemispheres of the brain, the left and right hemispheres which are separated by the Corpus Callosum. For example, the right side of the brain is responsible for emotions, musical aspects and controls the left part of the body, while the left side of the brain controls verbal and analytical skills while controlling the right part of the brain. There are three major parts of the brain, the hindbrain, forebrain and cerebral cortex. The cerebral cortex is broken down into four

people to consolidate recent information and events. Deep in the medial temporal lobes of the brain in complex vertebrates, amygdala is responsible for processing and memorizing emotional responses. Cerebral cortex is a thin layer of gray tissue on the surface of the central brain hemisphere. About two thirds of this

and they are: ● the cerebral cortex, ● limbic system, ● the cerebellum ● and the brain stem The cerebral cortex The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres). Sometimes the right hemisphere is related to creativity and the left hemisphere is related to logic abilities. It is divided into four sections called lobes, the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. This is the largest part of the brain. The cerebral cortex is associated

As neuroscience research progresses, the concept of the mind becomes of critical importance. The mind is usually considered to be a separate, nonmaterial entity compared to the physical neurons within the brain. However, the field of neuroscience is finding many connections between the physical nature of the brain and the supposed non-physical aspect of the human mind. In a sense, neuroscience seeks to understand the functioning of the mind in terms of the physical neuronal firings of the brain.

The telencephalon is at the front of the brain and is made up of the basil ganglia, the cerebral cortex, the olfactory bulb, and the corpus striatum. The functions of the telencephalon include: determining intelligence, personality, sense of smell, sense of touch, sensory impulse interpretations, organization and planning. The diencephalon is located in between the cerebral hemispheres and is greater than the midbrain. It is composed of the thalamus and hypothalamus structures. The thalamus

THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it

The four theories that are behind the cause of schizophrenia as referenced in the PowerPoint are Dopamine, Glutamate, Brain Abnormalities, and Nature vs. Nurture / More than one cause. 1. Dopamine Definition Dopamine is a neurotransmitter. It is one of the chemicals that is responsible for transmitting signals between the neurons of the brain. However, very few of those neurons actually produce dopamine. (psychologytoday.com) Theory The main theory concerning dopamine is that too much it can
