What body part is associated with the greatest amount of brain tissue in the somatosensory cortex?
Explanation: Lips is the part of the skin which can feel the sensations such as touch, heat, pressure and it covers the greatest amount of brain tissue. Somatosensory system is distributed throughout the major parts of the body.
Which stroke has affected the greatest amount of brain tissue?
Types of stroke The force of blood that escapes from the blood vessel can also damage surrounding brain tissue. Hemorrhagic stroke is the most serious kind of stroke. About 13% of all strokes are hemorrhagic. There are two types of hemorrhagic strokes: intracerebral and subarachnoid.
What parts of the body have the greatest amount of cortex devoted to them?
The areas of skin with the higher density of receptors (like the face, hands and fingers) have more cortical tissue devoted to them.
Which part of your brain is essential for receiving information that you are moving your legs?
amygdala
Which of the following parts of the brain is most active in decision making?
The Prefrontal Cortex (PFC) and hippocampus are the most critical parts of the human brain for decision making. The decision-making process contains four steps.
How does brain convey messages to different body parts?
Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses”. Impulses rush along tiny fibres, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.
Which type of muscles does the brain control?
The biggest part of the brain is the cerebrum. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to.
What carries messages from the sense organ to the brain?
The thalamus carries messages from the sensory organs like the eyes, ears, nose, and fingers to the cortex.
How are messages sent to and from the brain?
The average human brain contains about 86 billion nerve cells, called neurons. These are the building blocks of your brain. Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses”.
How does your body move does the brain send it messages to move explain and why?
Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When the impulses from the nerves stop, the muscle fibers slide back to their original positions.
What does the brain do as soon as it receive the information?
Answer Expert Verified If the brain received the information coming from the organ to sensory neurons and then it gives the reaction to the motor neurons and then send it in the other organs.
How is information sent to the brain?
Information is delivered into the spinal cord through the axon terminals of sensory neurons. Once in the spinal cord, the information may flow to motor neurons, to interneurons that pass it directly to motor neurons, or to interneurons that transmit the information to the brain.
How much information can the brain process?
The amount of domain-specific information that can be processed during a certain period of time has an estimated capacity ranging from 2 to 60 bits per second (bps) for attention, decision-making, perception, motion, and language, and up to 106 bps for sensory processing1,2,3,4,5,6,7.
How fast does the brain process information?
You might think it would be impossible to identify any images you see for such a short time. However, a team of neuroscientists from MIT has found that the human brain can process entire images that the eye sees for as little as 13 milliseconds — the first evidence of such rapid processing speed.
What part of the brain processes information?
temporal lobe
What are the three basic processes of memory?
Psychologists distinguish between three necessary stages in the learning and memory process: encoding, storage, and retrieval (Melton, 1963). Encoding is defined as the initial learning of information; storage refers to maintaining information over time; retrieval is the ability to access information when you need it.
What are the 6 parts of the brain?
6 Major Parts of the Brain and What They Do
- Frontal Lobes. At the front of the brain are the frontal lobes, and the part lying just behind the forehead is called the prefrontal cortex.
- Temporal Lobes.
- Occipital Lobes.
- Parietal Lobes.
- The Thalamus.
- The Hypothalamus.
- The Hippocampus.
- The Amygdala.
