NEOCORTICAL CHOLINERGIC NEURONS IN ELDERLY PEOPLE

The Lancet, 1977
Choline acetyltransferase activity (presynaptic cholinergic system) and high affinity binding of cholinergic antagonists (postsynaptic cholinergic system) were measured in brain tissue removed after death from both mentally normal and demented old people.

Cholinergic excitation of dendrites in neocortical neurons

Neuroscience, 1998
Discharge patterns were studied in response to iontophoretic application of acetylcholine to the soma and dendrites of 128 neocortical pyramidal neurons of layer V. Extracellular recordings were obtained from slices of the guinea-pig parietal cortex.

Expression of MEGF10 in cholinergic and glutamatergic neurons

Neuroscience Letters, 2017
Multiple-EGF like domains 10 (MEGF10) is the mammalian homologue of Draper, a Drosophila phagocytosis receptor that plays an important role in synapse elimination and cell type-specific recognition. However, the expression and function of MEGF10 in the brain remain to be elucidated.

Ontogeny of cholinergic neurons in the mouse forebrain

Journal of Comparative Neurology, 1989
AbstractThe development of cholinergic neurons in the mouse forebrain was studied by immunocytochemistry with a monoclonal antibody to choline acetyl‐transferase (ChAT), the rate‐limiting enzyme for acetylcholine synthesis. Since this antibody stained dividing cells in ventricular germinal zones as well as differentiating neurons, likely routes of ...

Development of cholinergic neurons of the rat retina

Developmental Biology, 1982
Abstract Biochemical and electrophysiological features of cholinergic neurons from the developing rat retina were analyzed in an attempt to identify important periods in the maturation of these neurons. Acetylcholine synthesis was assayed in intact, isolated retinas; choline acetyltransferase activity was measured in homogenates.

Biochemistry of Cholinergic Neurons

1975
The cholinergic system has not evoked the interest of psychopharmacologists to the same extent as the adrenergic or indoleaminergic systems of neurotransmission. It is not surprising that lay interest in hallucinogenesis has not included cholinergic agents such as the muscarinic drugs, because severe physiological reactions overlie their psychedelic ...

Cholinergic neurons in the rat substantia nigra

Neuroscience Letters, 1986
The distribution of choline acetyltransferase (ChAT)-like immunoreactivity (LI), demonstrated according to an avidin-biotin procedure, was evaluated in the substantia nigra (SN) of rats. Although ChAT positivity was considerably less in the nigral neuropil than in the interpeduncular nucleus, it was also higher, particularly in caudal pars reticulata ...

Cholinergic neurons in tunicates: An appraisal of the evidence

Comparative Biochemistry and Physiology, 1967
Abstract 1. 1. Isolated longitudinal muscles of Ciona intestinalis contract in response to applied cholinesters. Of several esters tried, ACh is the most effective; the threshold concentration is about 10 −7 g/ml. No consistent potentiation of the ACh occurs when eserine is applied. 2. 2. The action of ACh is blocked by banthine, atropine,

Cholinergic amacrine neurons of the dogfish retina

Visual Neuroscience, 1991
AbstractIn the mammalian retina, the dendritic arbors of cholinergic amacrine neurons have a unique starburst shape; these arbors lie in narrow sublaminae within the inner plexiform layer, where they provide input to a wide variety of ganglion cell types. Immunocytochemistry has been used to identify cholinergic cells in one poikilotherm, the goldfish (
