Behavioral state changes induced in Pleurobranchaea and Aplysia by serotonin.
TLDR
Serotonin is proposed as a likely mediator of behavioral state change in gastropods and increases in the frequency of numerous spontaneous behaviors in Aplysia californica were examined. Expand
Pleurobranchaea behavior: food finding and other aspects of feeding.
TLDR
Six experiments were performed which systematically describe aspects of the feeding behavior of Pleurobranchaea californica, a voracious carnivore, and it was found that locomotion in the presence of food chemical was not random; that reversals in direction were more frequent; and that if the chemical gradient were steep enough, animals turned in the direction of food.

Insulin inhibits pyramidal neurons in hippocampal slices
TLDR
Observations indicate that the inhibitory effect of insulin in this tissue may be insulin receptor-mediated and support a previously suggested functional role ofulin in the central nervous system. Expand
Saralasin increases activity of hippocampal neurons inhibited by angiotensin II
TLDR
Saralasin antagonizes AII whether its effects are inhibitory or excitatory, and the results indicate that this effect may be due to an inhibition of endogenous brain angiotensin II. Expand
Behavioral states and feeding in the gastropod Pleurobranchaea.
TLDR
The results of this investigation indicate that Pleurobranchaea is capable of a type of response plasticity: that of a reflex modification as a consequence of antecedent conditions. Expand
A biphasic excitatory response of hippocampal neurons to gonadotropin-releasing hormone.
TLDR
Using intracellular recording from 40 hippocampal CA1 pyramidal neurons, GnRH is found to elicit predominantly excitation, suggesting the neural response to GnRH may be involved in the initiation of the behavioral response since the termination of the long-duration response coincides with the onset of the behavior.

Chaotic activity during iron-induced 'epileptiform' discharge in rat hippocampal slices
TLDR
It is suggested that techniques of nonlinear dynamical analysis are a useful reverse-engineering tool for studying the in-vitro brain slice and concluded that neuronal circuits capable of displaying activity could exist at the level of the in vitro brain slice. Expand
3-D computer animation of electrophysiological responses
TLDR
Animation of 3-D plots of electrophysiological activity can provide instantaneous visual information on correlated changes in amplitude and latency over an entire brain slice and reduce a large number of complex wave forms to simple events and allow the simultaneous visualization of general patterns of activity in a large group of neurons.
