Detection of minute temperature transients by thermosensitive neurons in ants.
The antennae of leaf-cutting ants are equipped with sensilla coeloconica that house three receptor neurons, one of which is thermosensitive. Using convective heat (air at different temperatures), we investigated the physiological characteristics of the thermosensitive neuron associated with the sensilla coeloconica in the leaf-cutting ant Atta vollenweideri. The thermosensitive neuron very quic...
متن کاملSynaptophysin-Positive Neurons in External And Extreme Capsules in Human Brain
Purpose: Externaland extreme capsules are parts of cerebral white matter, and accordingto the classic knowledge they must have no neuronal cell bodies.This researchis designedto find neurons in the external and extreme capsules, and to determine that these neurons are functional or aberrant. Materitais and Methods: Ten adult normal human brains from both sexes were studied using 15,µm serial c...
متن کاملThermosensitive transient receptor potential channels in vagal afferent neurons of the mouse.
A number of transient receptor potential (TRP) channels has recently been shown to mediate cutaneous thermosensitivity. Sensitivity to warm and cool stimuli has been demonstrated in both human and animal gastrointestinal tract; however, the molecular mechanisms that underlie this have not been determined. Vagal afferent neurons with cell bodies in the nodose ganglion are known to mediate nonnoc...
متن کاملElectrophysiological characteristics of hippocampal CA1 neurons after spreading depression-triggered epileptic activity in brain slices
Introduction: A close link between spreading depression (SD) and several neurological diseases such as epilepsy could be demonstrated in many experimental studies. Epilepsy is among the most common brain disorders. Despite a large number of investigations, its mechanisms have not been yet well elucidated. Hippocampus is one of the important structures involved in seizures. The aim of this st...
متن کاملP30: Effects of Hemin on Ca2+Influx in Neurons of C57BL/6 Mouse Brain
Excitotoxicity results in a significant increase in Ca2+ influx; essentially from open N-Methyl-D-aspartate receptors (NMDARs) channels that cause a secondary rise in the intracellular Ca2+ concentration. It is correlated with neuronal death induced by Ca2+ overload. Dysfunction of NMDARs is associated with excitotoxic neuronal death in neurodegenerative disorders. In this study, the effects of...
