According to D.G. Jones, there are two types of brain death—whole brain death, the irreversible cessation of function of both the brain stem and higher parts of the brain—and higher-brain death, destruction of the cerebral hemispheres alone, with possible retention of brain stem function; and analogously, there are two types of brain birth ...
During the 1980s Michael Persinger stimulated the temporal lobes of human subjects with a weak magnetic field using an apparatus that popularly became known as the "God helmet" [14] and reported that many of his subjects claimed to experience a "sensed presence" during stimulation. [15]
One controversial proposal, the God gene hypothesis, states that some variants of a specific gene, the VMAT2 gene, predispose to spirituality. [46] Another view builds on the concept of the triune brain: the reptilian brain, the limbic system, and the neocortex, proposed by Paul D. MacLean. Collective religious belief draws upon the emotions of ...
It also occurs during testing for apnea—that is, suspension of external breathing and motion of the lung muscles—which is one of the criteria for determining brain death used for example by the American Academy of Neurology. [5] Occurrences of the Lazarus sign in intensive-care units have been mistaken for evidence of resuscitation of patients.
Brain regions with a high density of glucocorticoid receptors are especially vulnerable to the effects of early life stress, likely because glucocorticoids bind to these receptors during stress exposure, facilitating the development of survival responses at the cost of other important neural pathways. [64] Some examples of brain regions with ...
The Death of God and the Meaning of Life is a book by Julian Young, in which the author examines the meaning of life in today's secular, post-religious scientific world. [ 1 ] [ 2 ] See also
The process occurs from embryonic day 10 to 17 in mice and between gestational weeks seven to 18 in humans. [2] The cortex is the outermost layer of the brain and consists primarily of gray matter, or neuronal cell bodies. Interior areas of the brain consist of myelinated axons and appear as white matter.
This process is known as neurulation. [8] When the tube is closed at both ends it is filled with embryonic cerebrospinal fluid. [9] As the embryo develops, the anterior part of the neural tube expands and forms three primary brain vesicles, which become the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon).
