Brain

If the parietal cells were not functioning, you would expect decreased production of stomach acid (hydrochloric acid) and intrinsic factor, leading to impaired absorption of vitamin B12 and potentially causing symptoms like pernicious anemia, digestive issues, and malabsorption of nutrients.

Usually when we talk about reflexes -we are referring to two things: primary sensory processing (peripheral nervous system) followed by a motor response (central nervous system). These types of reflexes do not require higher-order cognitive function to occur - but the brain is made aware of what is going on, presumably so that we learn to avoid the harmful stimulus in the future.

For example, the accidental placement of a hand on a hot surface would usually result in an immediate withdrawal reflex. What's happening here is that pain receptors in the skin - in this case 'nociceptors' activated by thermal stimuli - send impulses to neurons in the spinal cord (the spinal cord is part of the central nervous system) that share circuits with neurons that control muscle contractions. These in turn fire, resulting in an immediate flexion (movement toward the body) of the affected limb.

we need identity because it can help us in many ways. It proves who we say we are. It can stop fraud and theft happening. It can also stop the use of false identity from criminals involved in terrorist activity. It can enable easier public access.

Multiple sclerosis is an autoimmune disorder characterized by extensive demyelination of the nerve fibers in the central nervous system. The immune system mistakenly attacks the myelin sheath, leading to impaired nerve function and potential neurological symptoms such as weakness, numbness, and vision problems. Treatment often involves medications to reduce inflammation and modify the immune response.

The nervous system carries messages to and from the brain through a network of neurons. Sensory neurons carry information from the body to the brain, while motor neurons carry signals from the brain to the body to control movement and other functions.

Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. It works to reduce the activity of neurons, thus promoting relaxation and reducing anxiety. Dysregulation of GABA signaling has been linked to various neurological conditions, such as epilepsy and anxiety disorders.

Yes, T2 and FLAIR signal hyperintensities are typically associated with white matter abnormalities in the brain. These hyperintensities can be seen in various conditions such as aging, vascular changes, inflammation, or demyelination. They can be important markers for diagnosing and monitoring neurological conditions.

The biological clock of the human body is the internal mechanism that regulates our sleep-wake cycle, also known as the circadian rhythm. This clock is influenced by external factors such as light, temperature, and social activities, and plays a crucial role in determining when we feel alert or sleepy. Disruptions to this clock, such as jet lag or shift work, can have negative effects on our health and well-being.

Acquired brain injuries in Canada have a significant impact on individuals, families, and the healthcare system. They can result in long-term physical, cognitive, and emotional impairments, affecting a person's ability to work, maintain relationships, and engage in daily activities. The cost of care and support for individuals with acquired brain injuries can be substantial, placing a strain on healthcare resources.

The parietal lobe receives sensory input for touch and body position. It integrates sensory information from different modalities, especially determining spatial sense and navigation. It is associated with movement, orientation, recognition, perception of stimuli.

The activity of the brain is crucial to the body's metabolism. Absence of brain function is the clinical definition of death.

However, using biofeedback and other techniques, individuals can reduce the activity level of various sections of the brain. This can highlight various "brainwaves" associated with activities within the central nervous system.

The brain looks like a oval cut in half. This 'oval' is wrinkly and gray ( when you wash off the blood.) Even though in pictures, different parts of the brain are different colors, in real life, it's all gray.
well the way i see it is its all wrinkaly and looks like a soltana

let \rho is density of phase fluid and v is velocity of phase fluid (velocity in a phase space!!)

we take the equation of continuity (we suppose "mass" of phase fluid is conserved) and using Hamilton equations (we suppose classical mechanical system)

[ dot{p_i} = -frac{partial H}{q_i} ]

[ dot{q_i} = +frac{partial H}{p_i} ]

we obtain the result

[ frac{mathrm{d}rho}{mathrm{d}t} = - rho,mathrm{div},v = -rho sum_i left( frac{partialdot{q_i}}{q_i} + frac{partialdot{p_i}}{p_i} right) = 0 ] let \rho is density of phase fluid and v is velocity of phase fluid (velocity in a phase space!!)

we take the equation of continuity (we suppose "mass" of phase fluid is conserved) and using Hamilton equations (we suppose classical mechanical system)

\[ \dot{p_i} = -\frac{\partial H}{q_i} \]

\[ \dot{q_i} = +\frac{\partial H}{p_i} \] we obtain the result

\[ \frac{\mathrm{d}\rho}{\mathrm{d}t} = - \rho\,\mathrm{div}\,v = -\rho \sum_i \left( \frac{\partial\dot{q_i}}{q_i} + \frac{\partial\dot{p_i}}{p_i} \right) = 0 \]

The cerebellum compares movements programmed by the cerebral cortex with what is actually happening. It constantly receives sensory impulses from muscles, tendons, joints, equilibrium receptors, and visual receptors. The cerebellum helps to smoooth and coordinate complex sequences of skeletal muscle contractions. It regulates posture and balance and is essential for all skilled motor activities, from catching a baseball to dancing.

This is actually unknown and all estimates are based solely on conjecture and very little experimental evidence for what a maximum usage would be and how to measure any given usage at any time.

The question also means different things at different times. So, more specificity would go a long way. For example, some people want to know how much of the human brain can be used at any given time

While others ask, what percent of the human brain, possible connections, and information tracts can be used total and what is the typical human percentage of those.

It's important to seek immediate veterinary attention as this could be a sign of a serious medical condition such as a stroke, spinal injury, or neurological issue that requires prompt treatment. A thorough physical examination, diagnostic tests, and imaging may be necessary to determine the cause and appropriate treatment.

The olfactory tract is the fiber tract involved with olfaction, responsible for carrying sensory information related to smell from the olfactory bulb to the olfactory cortex in the brain. This pathway allows for the recognition and interpretation of different odors.

Fibers are composed of long chains of molecules called polymers, which are made up of repeating smaller units called monomers. These polymers are typically derived from natural sources like plants or animals (such as cotton or silk) or are synthetically produced (such as polyester or nylon). The arrangement of these polymers and the way in which they are processed determine the properties of the fiber, such as strength, flexibility, and absorbency.

Many different parts of the brain are involved in memory recall (what people commonly call "remembering"). However, if one had to restrict his/her answer to a single brain structure, the hippocampus would probably be the one at the top of most neuroscientists' lists.

Removing the temporal lobe can result in memory loss, language difficulties, mood changes, and altered emotional responses. This can make a person more impulsive, aggressive, or socially inappropriate. The individual may also experience changes in their perception of reality and may struggle with understanding and interpreting social cues.

The brain is a organ. The brain is the organ that receives messages from the six senses; the touch sense, the seeing sense, the hearing sense, the smelling sense and the tasting senses. If you are asking 'Is the brain the largest organ?' Well, no. The largest organ is not the brain, or the chest, or the stomach. It is the skin.

It is possible that someone in the household used garlic in cooking or consumed it recently, leading to the lingering smell in the bathroom. Sometimes strong scents like garlic can be more noticeable in enclosed spaces like bathrooms. Ventilating the bathroom by opening a window or turning on a fan can help dissipate the smell.

People have brains to control their body's functions, process information, make decisions, and experience emotions. The brain is essential for cognition, movement, speech, and regulating bodily functions such as heartbeat and breathing.

Rock Paper Scissors is the key game...I think you can only get 20 if you are under 1 minute and 4 seconds in Rock paper scissors and of course you have to do pretty well in the other two games too, but that is a lot easier. I now get 20 (or 21) about 90% of the time, unless I really mess up on one of the tasks.
