Social interactions determine postural network sensitivity to 5-HT.
The excitability of the leg postural circuit and its response to serotonin (5-HT) were studied in vitro in thoracic nervous system preparations of dominant and subordinate male crayfishes. We demonstrate that the level of spontaneous tonic activity of depressor and levator motoneurons (MNs) (which control downward and upward movements of the leg, respectively) and the amplitude of their resista...
متن کاملDopamine and 5-HT receptor sensitivity does not correlate with neostriatal dopamine or 5-HT content.
To explore associations of neostriatal (NST) endogenous levels of dopamine (DA) and serotonin (5-HT) with sensitivity of their receptors, graded doses of 6-hydroxydopamine HBr (0 to 400 micrograms, ICV; 6-OHDA; desipramine pretreatment, 20 mg/kg IP) were given to rats between birth (P 0) and P 42. Numbers of vacuous chewing movements (VCMs) induced by SKF 38393 or m-chlorophenylpiperazine (m-CP...
متن کاملHeart rate within male crayfish: social interactions and effects of 5-HT.
Behaviors, such as those that establish dominant and subordinate social status, are thought to be driven by various neuromodulators and hormones. In crustaceans, the level of serotonin (5-HT) in the hemolymph is correlated with degree of aggressiveness. The crustacean heart is neurogenic and is modulated by neural secretion of 5-HT in the hemolymph, which bathes the cardiac tissue. We discuss a...
متن کاملSensitivity of transformed (phasic to tonic) motor neurons to the neuromodulator 5-HT.
Long-term adaptation resulting in a 'tonic-like' state can be induced in phasic motor neurons of the crayfish, Procambarus clarkii, by daily low-frequency stimulation [Lnenicka, G.A., Atwood, H.L., 1985b. Long-term facilitation and long-term adaptation at synapses of a crayfish phasic motoneuron. J. Neurobiol. 16, 97-110]. To test the hypothesis that motor neurons undergoing adaptation show inc...
متن کاملNeural Network Analysis of Postural Behavior of Young Swine to Determine the IR Thermal Comfort
and Implications A new method of classifying thermal comfort of young pigs was investigated that may be used to interactively control the micro-environment. The method uses the spectral features of swine postural images as inputs to a neural network which then classifies the corresponding thermal environment as cold, comfortable, or too warm for the pigs. The results show that the method has gr...
