∙ 6y agoIt is possible to take the idea of left/right differences within the brain too far. In the course of its evolution the left brain took on the crucial role of master interpreter. But other than that, the differences are in the lobes rather than each hemisphere.
Touch and pressure is found along the central sulcus of the parietal lobe, taste in the frontal lobe, smell in the temporal lobe, hearing also in the temporal lobe and vision in the occipital lobe.

In the central nervous system the communicates with and coordinates what happens in other parts of the brain?
Though I think the more correct answer is Cerebellum. For Penn Foster students, in the book it is Cerebum pg. 478 Cerebrum: "The cerebrum communicates with and coordinates the activities of the other parts of the brain." Though according to other sources, and according to two doctors I asked about this. Cerebum is the part of the brain that handles logic, imagination, reasoning ect. And CEREBELLUM is the part of the brain that communicates with the rest of the brain and body. So although in my opinion, cerebum is incorrect. For Penn Foster Students, the correct answer is A. Cerebrum
What is the location of the frontal lobe of the brain?
The frontal lobe is an area in the brain of humans and other mammals, located at the front of each cerebral hemisphere and positioned anterior to (in front of) the parietal lobe and superior and anterior to the temporal lobes. It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral (Sylvian) sulcus. The post-central gyrus, forming the posterior border of the frontal lobe, contains the primary motor cortex, which controls voluntary movements of specific body parts.
What part separates cerebellum hemispheres?
tentorium cerebelli separates your cerebellum from your cerebrum.
Describe the neural pathway beginning with the sensory receptors and ending with the cortex?
There are multiple pathways by which information from sensory receptors reaches the cerebral cortex. These pathways vary based on the type of information carried. For example, information from the body about pain and temperature travels via a pathway called the anterolateral system; information from the body about conscious body position sense and fine touch travels through the dorsal column-medial lemniscus system. Unconscious sensation of body position has its own pathways. The face has a separate set of pathways that mirror those for the rest of the body.
Where are the frontal lobes and what do they control?
The frontal lobes is the anterior-most portion of the cerebral cortex. It is responsible for executive function (planning, strategies, thinking ahead, social awareness) and is not fully developed in humans until around age 25. Humans have the largest frontal cortex relative to the rest of the cerebral cortex when compared to other animals, including non-human primates.
What is type I lissencephaly?
Type I, also known as classical lissencephaly, is distinguished by the smooth surface of the cerebral cortex and an abnormal four-layered cortex. Classical lissencephaly can be associated with abnormalities of the rest of the brain
What part of brain is responsible for voluntary movement?
The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature. Other areas of the cerebrum enable speech, judgment, thinking and reasoning, problem-solving, emotions and learning. Other functions relate to vision, hearing, touch and other senses.

Which vertebrates have the largest cerebrum relative to the rest of their brain?
Mammals.
How does the parietal work?
The parietal lobe is one of the four major lobes, regions of the cerebral cortex. This particular lobe works to process sensory information for other parts of the brain, and at its core works via the same electrical pulses the rest of the brain uses to function.
How does northern india differ from the rest of the region-?
Northern India differ from the rest of the region in that it has the Himalayas and a desert
What muscles do the cerebrum control?
All the voluntary muscles directly, and via the autonomic nervous system, all the rest.

What do the different parts of the human brain do?
CerebrumCerebellumLimbic SystemBrain StemThe nervous system is your body's decision and communication center.The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord... and from the spinal cord to the rest of your body. Sensory nerves gather information from the environment, send that info to the spinal cord, which then speed the message to the brain. The brain then makes sense of that message and fires off a response. Motor neurons deliver the instructions from the brain to the rest of your body. The spinal cord, made of a bundle of nerves running up and down the spine, is similar to a superhighway, speeding messages to and from the brain at every second.The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem.The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Here is a visual representation of the cortex:What do each of these lobes do?Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solvingParietal Lobe- associated with movement, orientation, recognition, perception of stimuliOccipital Lobe- associated with visual processingTemporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speechNote that the cerebral cortex is highly wrinkled. Essentially this makes the brain more efficient, because it can increase the surface area of the brain and the amount of neurons within it. We will discuss the relevance of the degree of cortical folding (or gyrencephalization) later.(Go here for more information about cortical folding)A deep furrow divides the cerebrum into two halves, known as the left and right hemispheres. The two hemispheres look mostly symmetrical yet it has been shown that each side functions slightly different than the other. Sometimes the right hemisphere is associated with creativity and the left hemispheres is associated with logic abilities. The corpus callosum is a bundle of axons which connects these two hemispheres.Nerve cells make up the gray surface of the cerebrum which is a little thicker than your thumb. White nerve fibers underneath carry signals between the nerve cells and other parts of the brain and body.The neocortex occupies the bulk of the cerebrum. This is a six-layered structure of the cerebral cortex which is only found in mammals. It is thought that the neocortex is a recently evolved structure, and is associated with "higher" information processing by more fully evolved animals (such as humans, primates, dolphins, etc). For more information about the neocortex, click here.The Cerebellum: The cerebellum, or "little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.The cerebellum is assumed to be much older than the cerebrum, evolutionarily. What do I mean by this? In other words, animals which scientists assume to have evolved prior to humans, for example reptiles, do have developed cerebellums. However, reptiles do not have neocortex. Go here for more discussion of the neocortex or go to the following web site for a more detailed look at evolution of brain structures and intelligence: "Ask the Experts": Evolution and IntelligenceLimbic System: The limbic system, often referred to as the "emotional brain", is found buried within the cerebrum. Like the cerebellum, evolutionarily the structure is rather old.This system contains the thalamus, hypothalamus, amygdala, and hippocampus. Here is a visual representation of this system, from a midsagittal view of the human brain:Click on the words to learn what these structures do:ThalamusHypothalamusAmygdalaHippocampusBrain Stem: Underneath the limbic system is the brain stem. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. Scientists say that this is the "simplest" part of human brains because animals' entire brains, such as reptiles (who appear early on the evolutionary scale) resemble our brain stem. Look at a good example of this here.The brain stem is made of the midbrain, pons, and medulla. Click on the words to learn what these structures do:MidbrainPonsMedulla
