What do convolutions in the cerebrum increase?
The convolutions seen in the cerebrum are important because they increase the surface area. Gray matter is composed of neuron cell bodies.
Where in the brain are the centers for these reflexes located?
The pons is also associated with the control of sleep cycles, and controls respiration and reflexes. It is located above the medulla, below the midbrain, and just in front of the cerebellum.
What is the striatum and how is it related to the fibers of the internal capsule quizlet?
WHAT IS THE CORPUS STRIATUM, AND HOW IS IT RELATED TO THE FIBERS OF THE INTERNAL CAPSULE? FIBERS OF THE INTERNAL CAPSULE PASS THROUGH THE DIENCEPHALON AND BASAL NUCLEI, GIVES THEM STRIPED APPEARANCE. THEREFORE, THEY ARE RELATED AND REFFERED TO AS CORPUS STRIATUM (STRIPED BODY).
What is the most important autonomic center of brain?
The hypothalamus is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control. The major pathway from the hypothalamus for autonomic control is the dorsal longitudinal fasciculus.
What part of the brain is for thinking?
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.
What is the grey matter?
Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses. This brain tissue is abundant in the cerebellum, cerebrum, and brain stem. It also forms a butterfly-shaped portion of the central spinal cord.
Can the brain stem heal itself?
Once the brain stem has permanently stopped functioning, there's no way of reversing it and the heart will eventually stop beating, even if a ventilator continues to be used.
Can you live with just a brain stem?
Of course the brain stem which sits at the bottom of the brain and connects to the spine was normal. Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it.
How is the striatum related to the fibers of the internal capsule?
The internal capsule consists of projection fibres passing through the corpus striatum. It forms a knee-bend (genu) around the apex of the lentiform nucleus and is V-shaped on axial (horizontal) sections.
What is the striatum responsible for in your brain?
In conclusion, the striatum contains neuronal activity related to movements, rewards and the conjunction of both movement and reward. These neuronal representations serve many functions like goal directed movements and decision making.
Which part of the brain controls speech?
Frontal lobe. The frontal lobe contains Broca's area, which is associated with speech ability.
Which half of the brain controls speech?
left hemisphere In general, the left hemisphere or side of the brain is responsible for language and speech. Because of this, it has been called the "dominant" hemisphere. The right hemisphere plays a large part in interpreting visual information and spatial processing.
What part of the brain controls pain?
Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships (where one's body is compared with objects around the person). The parietal lobe is also involved in interpreting pain and touch in the body.
What is the most amazing thing about the brain?
Your brain's storage capacity is considered virtually unlimited. Research suggests the human brain consists of about 86 billion neurons. Each neuron forms connections to other neurons, which could add up to 1 quadrillion (1,000 trillion) connections. Over time, these neurons can combine, increasing storage capacity.
What is spiral cord?
The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord carries nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body.
What is white brain matter?
White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.
How do you reverse brain damage?
While damage to the brain cannot be reversed, functions affected by TBI can be recovered thanks to the brain's natural ability to rewire itself….In order to promote neuroplasticity after brain injury, individuals should focus on:
- Repetition. …
- Specificity. …
- Intensity.

Can brain cells grow back if they are damaged?
In the brain, the damaged cells are nerve cells (brain cells) known as neurons and neurons cannot regenerate. The damaged area gets necrosed (tissue death) and it is never the same as it was before. When the brain gets injured, you are often left with disabilities that persist for the rest of your life.
Can brain dead person open eyes?
For example, they may open their eyes but not respond to their surroundings. In rare cases, a person in a vegetative state may show some sense of response that can be detected using a brain scan, but not be able to interact with their surroundings.
Can brain stem damage be repaired?
Once the brain stem has permanently stopped functioning, there's no way of reversing it and the heart will eventually stop beating, even if a ventilator continues to be used.
What symptoms would you expect to see in a patient with damage to the basal nuclei?
Damage to the basal ganglia cells may cause problems controlling speech, movement, and posture. This combination of symptoms is called parkinsonism. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement.
What part of the brain is pleasure?
Scientists have long believed that the central amygdala, a structure located deep within the brain, is linked with fear and responses to unpleasant events. However, a team of MIT neuroscientists has now discovered a circuit in this structure that responds to rewarding events.
What does the amygdala do?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
How soon does speech return after a stroke?
Many recover within a few months after the stroke, but up to 60% still have language impairments more than six months after a stroke, a condition known as chronic aphasia.
Can speech return to normal after a stroke?
You can't predict how a person will recover from a stroke. But usually, communication problems improve naturally over weeks and months. The brain can often adapt and pick up new skills to make up for some of what it lost. However, some people do have lasting communication problems.
Which side of the brain is worse to have a stroke?
The terms Left Brain Stroke and Right Brain Stroke refer to the side of the brain where the obstruction causing the stroke occurs. There is not a worse or better side to have a stroke on as both sides control many important functions, but a more severe stroke will result in amplified effects.
Which part of brain is responsible for memory?
Hippocampus. A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space.
Which chemical is released during pain?
Endorphins are hormones that are released when your body feels pain or stress. They are produced in your brain and act as messengers in your body.
How do you train your brain to stop pain?
The following techniques can help you take your mind off the pain and may help to override established pain signals.
- Deep breathing. …
- Eliciting the relaxation response. …
- Meditation with guided imagery. …
- Mindfulness. …
- Yoga and tai chi. …
- Positive thinking.

What Colour is the brain?
The human brain color physically appears to be white, black, and red-pinkish while it is alive and pulsating. Images of pink brains are relative to its actual state. The brains we see in movies are detached from the blood and oxygen flow result to exhibit white, gray, or have a yellow shadow.
