The neural basis of the behaviorally relevant N1 component of the somatosensory-evoked potential in SI cortex of awake monkeys: evidence that backward cortical projections signal conscious touch sensation.

Studies of touch intensity discrimination in monkeys have identified a component of the somatosensory-evoked cortical potential, N1, generated within 50 ms of the stimulus, that predicts their behavioral performance. This study employed…

Coding the meaning of sounds: contextual modulation of auditory responses in the basolateral amygdala.

Female mice emit a low-frequency harmonic (LFH) call in association with distinct behavioral contexts: mating and physical threat or pain. Here we report the results of acoustic, behavioral, and neurophysiological studies of the contextual analysis…

Development of social vocalizations in mice.

Adult mice are highly vocal animals, with both males and females vocalizing in same sex and cross sex social encounters. Mouse pups are also highly vocal, producing isolation vocalizations when they are cold or removed from the nest. This study…

A novel coding mechanism for social vocalizations in the lateral amygdala.

The amygdala plays a central role in evaluating the significance of acoustic signals and coordinating the appropriate behavioral responses. To understand how amygdalar responses modulate auditory processing and drive emotional expression, we assessed…

Connecting the dots–establishing causality between chronic stress, depression, and cardiovascular disease.

Daily spontaneous running alters behavioral and neurochemical indexes of nigrostriatal function.

Behavioral and neurochemical indexes of nigrostriatal dopaminergic function were compared between sedentary control rats (n = 12) and daily spontaneous running (DSR) male rats (n = 10). Nine weeks of DSR did not significantly alter body, heart,…

Daily exercise attenuates the sympathetic component of the arterial baroreflex control of heart rate.

The influence of daily spontaneous running (DSR) on the sympathetic (SC) and parasympathetic components of the arterial baroreflex control of heart rate (HR) was examined in 16 female Long Evans rats [8 sedentary (SED) and 8 DSR]. After

Daily exercise attenuates the sympathetic nerve response to exercise by enhancing cardiac afferents.

"Central command" may initiate the sympathoexcitatory responses at the onset of exercise by shifting the operating point of the arterial baroreflex toward higher pressures. Daily exercise (DE) attenuates the sympathoexcitatory responses to submaximal…

Flight feather attachment in rock pigeons (Columba livia): covert feathers and smooth muscle coordinate a morphing wing.

Mechanisms for passively coordinating forelimb movements and flight feather abduction and adduction have been described separately from both in vivo and ex vivo studies. Skeletal coordination has been identified as a way for birds to simplify the…

Onset of exercise increases lumbar sympathetic nerve activity in rats.

We hypothesized that lumbar sympathetic nerve activity (LSNA) increases at the onset of whole-body dynamic exercise in the rat. To test this hypothesis, we recorded LSNA, heart rate (HR), and arterial pressure (AP) at rest and during a graded…

Gender and the behavioral manifestations of neuropathic pain.

A model of peripheral nerve injury was used to study gender differences in the development and progression of chronic constriction injury (CCI)-induced hyperalgesia and allodynia in male and female Fischer 344 FBNF1 hybrid rats. Rats were randomly…

Prenatal stress changes courtship vocalizations and bone mineral density in mice.

Stress during the prenatal period has various effects on social and sexual behavior in both human and animal offspring. The present study examines the effects of chronic restraint stress in the second vs third trimester in pregnancy and…

Selectivity and persistent firing responses to social vocalizations in the basolateral amygdala.

This study examined responsiveness to acoustic stimuli among neurons of the basolateral amygdala. While recording from single neurons in awake mustached bats (Pteronotus parnellii), we presented a wide range of acoustic stimuli including tonal,…

Lack of an inhibitory effect of hyperprolactinemia on androgen-dependent marking.

An experiment was performed to determine if hyperprolactinemia (chronically elevated serum prolactin levels), which inhibits testosterone-activated male sexual activity, also affects other androgen-dependent behaviors. Thus defecation and urine…

Neuropathic pain in aged rats: behavioral responses and astrocytic activation.

We used the Bennett and Xie (1988) model of chronic neuropathic pain to study the effect of age on thermal and tactile sensitivity and on astrocytic activation in the dorsal horn of the spinal cord after nerve injury. Fischer 344 FBNF1 hybrid rats in…

Estrogen receptor-alpha and neural circuits to the spinal cord during pregnancy.

Estrogen receptor immunoreactivity and mRNAs are present in spinal cord neurons in locations that are associated with sensory and autonomic innervation of female reproductive organs. The present study was undertaken to examine the expression of…

Etiology of reactive arthritis in Pan paniscus, P. troglodytes troglodytes, and P. troglodytes schweinfurthii.

The character of arthritis has not received the same attention in Pan paniscus as it has in P. troglodytes. Reactive arthritis (a form of spondyloarthropathy) in the latter has been considered to be either a sexually transmitted or an…
