What is fore-brain?
The forebrain is a term used to designate the area of the brain that is responsible for the brain's critical and complex thinking, judgment making, and controlling impulses.
The part of the brain that translates the impulses that the eyes receive into vision is the?
Association area of the cerebral cortex
Where do impulses to the muscles originate?
The "impulses" to skeletal muscles come primarily from alpha motor neurons in the ventral horn of the spinal cord. These neurons release acetylcholine on the muscles, which causes sodium to enter the muscle, leading to contraction. The alpha motor neurons themselves get input from several sources, such as the primary motor area in the cerebral cortex of the brain. However, even this brain area gets input from other brain areas, including sensory areas. In a certain sense, the impulses to the muscles "originate" from the environment in the form of sensory signals.
What transmits sound from the inner ear to the brain?
The auditory nerve transmits sound signals from the inner ear to the brain. It carries electrical impulses generated by the hair cells in the cochlea to the brainstem, where the signals are further processed and interpreted as sound.
What happens in deep brain stimulation?
In deep brain stimulation, electrodes are surgically implanted in specific areas of the brain and connected to a device similar to a pacemaker. Electrical impulses are then delivered to these areas to help regulate abnormal brain activity and improve symptoms of movement disorders like Parkinson's disease or essential tremor. This treatment can help reduce symptoms such as tremors, stiffness, and difficulty with movement.
Can you see a real ghost?
No. Mostly you see something in an area where there is heavy electromagnetic surges due to the magnetic field of the Earth and the Sun's solar flares so the electrical impulses in your brain have to adjust themselves, and due to the mood you are in plus the atmosphere of the envirment, your mind will, so to say, play tricks on you.
How do spikes and receptors interact?
It reacts in these following steps: 1) A spike (the stimulus) is touched by receptors in the skin. 2) Receptors in the skin detect the stimulus and send electrical impulses down neurones to the sensory neurone. 3) The sensory neurone will pass these electrical signals to the CNS (Central Nervous System). 4) The CNS will pass these electrical signals to the motor neurone which once connected to the brain (through nervous cells reaching the carotid area of the body), the brain will detect and understand the feeling of the spike and will send this information the receptors.
What does transcutaneous electrical nerve stimulation do?
Transcutaneous electrical nerve stimulation (TENS) uses a battery-powered device generating weak electrical impulses applied along the course of affected nerves to block pain signals traveling to the brain.
What fiber tracts carry signals about voluntary movement to the spinal cord?
The basal ganglion are responsible for carrying the impulses from the cerebral cortex to the cerebellum. The impulses pass through the brain stem in an area called the pons where they cross-over and switch sides of the body. This is why your left side of your brain controls the right side, and visa versa.
What nerve carries the action potentials from the ganglion cells to the thalamus of the brain?
The optic nerves carry the impulses from the eyes to the visual area of the thalamus.
Is the hypothalamus is the area where afferent impulses from all senses and all parts of the body are sorted out and relayed to the appropriate area of the sensory cortex?
No, the hypothalamus is a region of the brain responsible for regulating various physiological processes such as temperature, hunger, and thirst. Afferent impulses from all senses and body parts are primarily sorted and relayed in the thalamus before being transmitted to the appropriate area of the sensory cortex.
What nerve is carrying impulses from the eye to the thalamus?
The optic nerves carry the impulses from the eyes to the visual area of the thalamus.
