Lead exposure damages cells in the hippocampus, a part of the brain involved in memory. Hippocampi of lead-exposed rats (bottom) show structural damage such as irregular nuclei (IN) and denaturation of myelin (DMS) compared to controls (top). [201] The brain is the organ most sensitive to lead exposure. [77]
Lead's high density, atomic number, and formability form the basis for use of lead as a barrier that absorbs sound, vibration, and radiation. [229] Lead has no natural resonance frequencies; [229] as a result, sheet-lead is used as a sound deadening layer in the walls, floors, and ceilings of sound studios. [230]
In neuroanatomy, the optic chiasm, or optic chiasma (/ ɒ p t ɪ k k aɪ æ z əm /; from Greek χίασμα 'crossing', from Ancient Greek χιάζω 'to mark with an X'), is the part of the brain where the optic nerves cross. It is located at the bottom of the brain immediately inferior to the hypothalamus. [1]
"Lead can be damaging to the developing brain," Calello says. "While adults can have effects from excess lead exposure as well, the effects are more severe in children and occur at lower levels."
Extended exposure can cause anemia, high blood pressure, lung damage, cancer, fertility problems, tooth and bone loss, kidney problems, brain damage, and even death. Lead is often found in paint ...
Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
The output neurons of the nucleus accumbens send axonal projections to the basal ganglia and the ventral analog of the globus pallidus, known as the ventral pallidum (VP). ). The VP, in turn, projects to the medial dorsal nucleus of the dorsal thalamus, which projects to the prefrontal cortex as well as back to the ventral and to dorsal stri
