On the base of the frontal lobe it overlies the anterior perforated substance through which the striate arteries enter the interior of the brain. On the temporal lobe the olfactory cortex covers the rostral portion of the parahippocampal gyrus including a medial bulge known as the uncus or uncinate gyrus. From the olfactory cortex, olfactory information is relayed via the mediodorsal nucleus of the thalamus to the insular and orbitofrontal cortex. The insular cortex, which is buried in the depths of the Sylvian fissure, also
Hemispheric specialization refers to the dominance of one hemisphere of the brain in specific functions, such as language, emotions, motor control and so on ( Feldman, 2009). The brain is a part of the central nervous system which is the subdivision of the nervous system. Its main role is to process sensory information from various parts of the body to make them meaningful. The brain receives sensory information from all parts of the body through the spinal cord (Passer & Smith, 2009). Basically, the brain is divided into three parts.
The cerebrum, which develops from the front portion of the forebrain, is the largest part of the mature brain. It consists of two large masses, called cerebral hemispheres, which are almost mirror images of each other. They are connected by a deep bridge of nerve fibers called the corpus callosum and are separated by a layer called the falx cerebri. The cerebrum or cortex is associated with higher brain function such as thought and action. White matter is a component of the central nervous system, in the brain and superficial spinal cord, and consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers.
To better understand Biopsychology, one has to learn about the three most crucial parts, which are the brain, neurotransmitters, and the nervous system. The brain is in-charge for the cognition, senses, motor abilities, and feelings through its’ four lobes of the
(2000) defines the frontal lobe as the part of the brain that controls important cognitive skills in humans. It is located in the front of the brain deep to the frontal bone of the skull. It plays an integral role for example the following functions that is memory formation, emotions, decision making/reasoning, personality, conscious thought, behaviour, planning, organizing, problem solving. The frontal lobe is the most uniquely human of all the brain structures. It is also responsible for primary motor function, or our ability to consciously move our muscles, and the two key areas related to speech, including Broca’s area.
The frontal lobe’s main functions are movement control and language production that thrive from the primary motor cortex. Whereas Wernicke’s area is located on the left side of the temporal lobe, called superior temporal gyrus, that is link with the auditory cortex, which associates memories, comprehension of language, emotion, and sensory input. There is a difference in aphasia between Broca’s and Wernicke’s area. Once the Broca’s area is damaged the person would have
Parietal lobe - responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness. Occipital lobe- responsible for processing information related to vision Cerebrum lobe - biggest part of the Brain its role is memory, attention, thought, and our consciousness, senses and movement. Hippocampus = responsible for memory forming, organizing and storing and emotions. 3. Explain why depression, delirium and age related memory impairment may be mistaken for dementia.
This is the part of the brain where the ascending and descending tracts are housed. This house creates a bulge that is called pons. This is located on the brains stem’s ventral surface. These pons are what make most of this division of the brain. The cerebellum is another large division that is located on the brain stem's dorsal surface.
Among them, cerebrum is characteristic of the human being in the three parts of the brain. The cerebrum is a section of the brain where Cognitive functions begins. Cerebrum also breaks into four parts such as occipital lobe, temporal cortex, parietal lobe, and frontal cortex. Each of these areas has a particular task that they are responsible for; however, most of these areas serve a specific cognitive function (CNBC, 2009). These functions are speaking, emotion, problem- solving, learning, and perception.
The Brain and Behavior Sandra Bradley BEH/225 12/14/2014 Latoshia Stamps The frontal lobes and temporal lobes have different roles regarding behavior. The frontal lobes are located in the front of the brain and are involved with “higher mental abilities and play a role in your sense of self” (Coon, D. & Mitterer, J. O., 2013). They are involved with higher mental abilities such as planning and reasoning, problem solving and judgment, impulse control and language, and social and sexual behavior. There is also an area located at the rear of the frontal lobes called the primary motor cortex. This area of the brain control motor function and directs the body’s muscles.
