The current study examines how environmental factors can promote an epigenetic event to promote an alteration in mate preference behavior.
Interestingly, previous analysis of F3 generation control and vinclozolin lineage female and male rats (i.e. prior to the onset of disease) demonstrated an alteration in mate preference behavior [ 27].
Childhood exposure to lead, even at relatively low levels (Canfield et al. 2003), results in a decline of cognitive function that persists into adulthood and that manifests as a persistent lowering of IQ score plus alteration in behavior (Needleman et al. 1990).
This produces a feeling of discomfort leading to an alteration in one of the attitudes, beliefs or behaviors to reduce the discomfort and restore balance etc.
As described above, feeding flies hydrogen peroxide caused an increase in activity and alterations in behavior, beginning approximately 11 minutes after first exposure.
It is unclear whether these alterations in behavior are a consequence of the existence of VNO-dependent neural circuits underlying gender-specific behaviors [ 16] or, alternatively, whether those behaviors are caused by hormonal changes [ 21].
Using a range of tests we have studied alterations in behavior with advancing age in female C57BL/6 (of Jackson origin), the golden standard on which most genetically engineered mice are back-crossed.
These changes reflect alterations in behavior that affect offspring in a sex-specific manner.
These, in turn, translate into alterations in behavior such as increased startle response or anxiety.
Administration of the N-methyl-d-aspartate (NMDA) antagonist phencyclidine (PCP) may produce alterations in behavior that resemble those that have been observed in animal models of schizophrenia.
Results indicated that exposure to 56Fe particles can produce alterations in behavior and neuronal signaling and that these alterations may be more apparent in older organisms, a finding which suggests that the aging brain may be more susceptible to the deleterious effects of irradiation on performance.
