Pericytes and renal mesangial cells are some examples of modified myofibroblast-like cells. Myofibroblasts may interfere with the propagation of electrical signals [5] controlling heart rhythm, [6] leading to arrhythmia in both patients who have suffered a heart attack and in foetuses. Ursodiol is a promising drug for this condition. [7]
In one study, single-cell recordings were taken from electrodes implanted in a rat's hippocampus, and it was found that certain neurons responded strongly only when the rat was in certain locations. These cells are called place cells, and collections of these cells can be considered to be mental maps. Individual place cells do not only respond ...
The hippocampus, as the medial pallium, is a structure found in all vertebrates. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms.
Hippocampus in the human brain Nissl-stained coronal section of the brain of a macaque monkey, showing hippocampal formation and subfields (circled). Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain.
Meta-positron emission tomography (PET) analysis has lent support toward a division of the hippocampus between caudal and rostral regions. [2]Scans have demonstrated a uniform variation in blood flow distribution within the hippocampus (and the medial temporal lobe broadly) during the separate processes of episodic encoding and retrieval.

Additionally, over an 8-year period, from 2016 to 2024, the brain samples showed a 50% higher total of microplastics — which reflected a similar increase in the rate of microplastics found in ...
The dorsal hippocampus was found to be an important component for the generation of new neurons, called adult-born granules (GC), in adolescence and adulthood. [17] These new neurons contribute to pattern separation in spatial memory, increasing the firing in cell networks, and overall causing stronger memory formations.
In total, the researchers found 16 plastic fibers and particles in the tissues. The smallest were slimmer than the diameter of a human red blood cell, which measures about 8 micrometers. The most ...
