The brain doesn’t shut off like a light switch, even as death approaches. While other bodily organs—namely the heart and lungs—have sudden stops, the brain flickers on through active neurons ...
Dyschronometria, also called dyschronia, is a condition of cerebellar dysfunction in which an individual cannot accurately estimate the amount of time that has passed (i.e., distorted time perception). It is associated with cerebellar ataxia, [1] [2] when the cerebellum
Brain death is used as an indicator of legal death in many jurisdictions, [6] but it is defined inconsistently and often confused by the public. [7] Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations.
A death rattle is noisy breathing that often occurs in someone near death. [1] Accumulation of fluids such as saliva and bronchial secretions in the throat and upper airways is the cause. [ 2 ] Those who are dying may lose their ability to swallow and may have increased production of bronchial secretions, resulting in such an accumulation. [ 3 ]
Like the knee jerk reflex, the Lazarus sign is an example of a reflex mediated by a reflex arc—a neural pathway which passes via the spinal column but not through the brain. As a consequence, the movement is possible in brain-dead patients whose organs have been kept functioning by life-support machines , precluding the use of complex ...
Scientists have managed to make death even scarier. According to a team of scientists in New York, the human brain is still very active after death, which means there's a chance you could actually ...
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
[10] Like lower regions, this region of the brain has combination-sensitive neurons that have nonlinear responses to stimuli. [ 6 ] Recent studies conducted in bats and other mammals have revealed that the ability to process and interpret modulation in frequencies primarily occurs in the superior and middle temporal gyri of the temporal lobe.
