What are symptoms of late stage kuru?
Late stage kuru symptoms can include difficulty swallowing, severe tremors, difficulty walking, and emotional instability. These symptoms are indicative of advanced neurological damage caused by the kuru prion disease.
What are part of the brain is concerned with olfaction?
The olfactory bulb and the olfactory cortex, located in the temporal lobe of the brain, are primarily responsible for processing smell information. The olfactory bulb receives sensory input from the nose and sends signals to the olfactory cortex for further processing and interpretation of smells.
Is moderate to severe hypoperfusion in frontal and both temporal lobes very bad?
Yes, this may be a cause of permanent and severe brain damage. Hypoperfusion means there is an insufficient amount of blood flowing to those parts of the brain. The frontal lobe has neurons that function to regulate emotion and integrate multiple sources of information. The temporal lobes are involved in speech, movement, language and artistic expression.
If we could find a definite answer for fundamental sensor of fundamental particle, how it senses it;s own existence,as well as it;s environment,we might find definite answers for nerve and brain system activity.
We are able to learn a new language or a new sport because of the brain's ability towards?
Neuroplasticity, a term that describes the brain's ability to reorganize and create new neural connections throughout life. This enables us to learn and adapt to new skills and information, such as languages or sports, by forming and strengthening neural pathways related to these activities.
What part of the brain enables us to relax?
The parasympathetic nervous system, which is part of the autonomic nervous system, helps regulate relaxation by slowing heart rate, promoting digestion, and conserving energy. The prefrontal cortex also plays a role in relaxation by helping to regulate emotions and behavior.
Brain waves are recordings of activity in the?
Brain waves are recordings of activity in the brain, specifically the electrical activity generated by neurons communicating with each other. They are typically measured using electroencephalography (EEG) and can provide insight into cognitive processes, emotional states, and neurological conditions.
What is the largest portion of the primary motor and sensory cortex devoted to?
The largest portion of the primary motor and sensory cortex is devoted to the face and hands. This is because these areas have fine motor control and require greater sensory input for activities of daily living and interactions with the environment.
We dream to sort out complicated thoughts and feelings, to store important memories, and to get rid of unimportant memories. We might have nightmares because we anxious, worried, or it's a reaction to a medication
What structure in the brainstem is required for life?
The medulla oblongata is a crucial structure in the brainstem that is required for life. It plays a vital role in regulating essential functions such as breathing, heart rate, and blood pressure. Damage to the medulla can be life-threatening.
What forms the outer layer of the cerebral cortex?
The outer layer of the cerebral cortex is formed by gray matter, which consists of nerve cell bodies, dendrites, and synapses. This layer is crucial for processing information in the brain, including sensory perception, motor function, and higher cognitive functions.
What activity would require the coordination of both hemispheres of the brain?
Playing a musical instrument, such as the piano or guitar, would require the coordination of both hemispheres of the brain. This is because the left hemisphere is responsible for logical tasks like reading music and the right hemisphere controls the creative aspects like rhythm and expression.
What part of brain filters out background noise?
The auditory cortex in the brain is responsible for filtering out background noise and focusing on specific sounds. It processes and distinguishes different sounds to help us pay attention to what is important while ignoring irrelevant noise. This function helps us understand speech, music, and other auditory stimuli in various environments.
What is the amygdala responsible for?
The amygdala is responsible for processing emotions, particularly fear and threat detection. It plays a key role in the brain's response to stress and helps regulate emotional responses to stimuli in the environment.
A cerebral lobe not visible in an ordinary external inspection?
The parietal lobe is not typically visible in an external inspection as it is located deep within the brain, underneath other brain structures. It plays a critical role in processing sensory information and spatial awareness, but its functions are not readily apparent from the outside.
How does lack of oxygen to the brain cause seizures?
When the brain is deprived of oxygen, it cannot function properly, leading to an imbalance in the electrical activity of the brain. This can trigger abnormal neuronal firing, resulting in seizures. Seizures are a sign of brain dysfunction and can occur as a response to the stress caused by lack of oxygen.
How did Broca and Wernicke determine the location of key language areas in the brain?
Broca and Wernicke determined the location of key language areas in the brain by studying patients with language deficits due to brain injuries. Broca identified a brain region in the frontal lobe responsible for speech production, now known as Broca's area. Wernicke identified a region in the temporal lobe responsible for language comprehension, now known as Wernicke's area.
How many words can the human brain process per minute?
Functional word processing, "Reading" is the general way our brain processes words. Under this assumption, you're asking about the maximum reading comprehension speed. The action potential of the human brain varies across many demographics. Factors are dependent on brain development, disabilities and genetic predispositions.
The average human brain, within a normal standard distribution model, can process between 5 and 6 times your sustainable typing speed. Typing speed seem to be indicative of our word processing efficiency, but not entirely dependant.
If you can type 60 (wpm) @ 90%, then reading comprehension is likely 300-350 wpm @90%. (average)
The upper range for effective word comprehension is between 600-715 wpm. (very rare)
Does neurologist deals with problem with the brain?
Yes, neurologists specialize in diagnosing and treating disorders of the nervous system, which includes the brain, spinal cord, and nerves. They can address a wide range of conditions that affect the brain, such as headaches, seizures, strokes, and neurodegenerative diseases like Alzheimer's and Parkinson's.
neuron. Neurons are specialized cells that process and transmit information through electrical and chemical signals in the nervous system. They have a unique structure that allows them to efficiently communicate with other neurons, facilitating the functioning of the nervous system.
What is the most prolonged development of any region of the brain?
The prefrontal cortex has one of the longest developmental trajectories of any brain region, continuing to mature well into young adulthood. This area is involved in higher-order cognitive functions such as decision-making, impulse control, and social behavior.
What part of the brain is damaged that impairs consciousness and awake and sleep cycles?
Damage to the reticular activating system (RAS) in the brainstem can impair consciousness and disrupt the sleep-wake cycle. The RAS plays a crucial role in regulating arousal and alertness by filtering sensory information and sending signals to the cerebral cortex to maintain wakefulness.
