Electrophysiological evidence

One elegant study (Bassareo and Di Chiara, 1999) has shown that the medial, so-called shell region of the nucleus accumbens responds to presentations of novel palatable food with increased concentrations of extracellular DA, a response which habituates even though the rat may be consuming more food with repeated presentation. The DA response

Studies on teleost fish and mammals have demonstrated the existence of non-rod, non-cone ocular photoreceptors. In the case of VA opsin in the roach, electrophysiological evidence suggests that one function of this photosensory photopigment is to modulate the activity of retinal horizontal cells. To what end remains unclear, but this fits with the general role of horizontal cells in the teleost...

P americana is one of just a few species of insects in which both peripheral and central olfactory processing have been studied. In contrast to many short-lived lepidopterans, in which the male antenna is highly specialized for sex pheromone reception, the antennae of male cockroaches contain numerous food-responsive sensilla. In addition to olfactory sensilla, the antennae also house mechano-, hygro-and thermoreceptors, as well as contact chemoreceptors (Schaller, 1978 review Boeckh et al., 1984). Extensive ultrastructural and electrophysiological evidence has demonstrated that morphologically defined sensillum types house receptor cells of specific functional types (Sass, 1976, 1978, 1983 Schaller, 1978 Selzer, 1981, 1984 review Boeckh and Ernst, 1987). Boeckh and Ernst (1987) defined 25 types of cell according to their odor spectra, but of the 65 500 chemo- and mechanosensory sensilla on the antenna of adult male P. americana, an estimated 37 000 house cells that respond to periplanone-A and periplanone-B. 

So far, we have mostly emphasized the role of activation in raising or lowering the probability that the brain-mind will be more or less conscious. The electrophysiological evidence of a centrencephalic activating system is echoed by data from recent imaging studies that show that as our mental lights go out, the blood flow to these same core structures declines dramatically.

There is anatomical and pharmacological evidence that 5-HT1B receptors have an axonal localization in different cerebral pathways and inhibit neurotransmitter release (10,149,158,159). Therefore, most electrophysiological evidence of the role of 5-HT1B receptors in neuronal function is based on the assessment of inhibitory actions on evoked synaptic potentials or currents in target neurons, whereas neurochemical studies have examined direct effects on neurotransmitter release.

A vast amount of electrophysiological evidence has accumulated over the past several years demonstrating that auditory responses to microwave pulses are similar to those evoked by conventional acoustic pulses (6,7, U, 13,1 A, 15). Furthermore, they show that microwave acoustic effect is mediated by an electromechanical interaction which is initiated outside or at the cochlea. An alternative hypothesis involves direct stimulation of the cochlear nerve or neurons at higher levels along the auditory pathway. This latter mechanism is probably not at work as I shall presently demonstrate.
