Navigating with fingers and feet: analysis of human (Homo sapiens) and rat (Rattus norvegicus) movement organization during nonvisual spatial tasks.
The current set of studies examines the contribution of movement segmentation to self-movement cue processing for estimating direction and distance to a start location in humans and rats. Experiments 1 and 2 examined the extent that ambulatory dead reckoning tasks can be adapted to the manipulatory scale in humans. Experiments 3 and 4 investigated the performance of rats in similar tasks at the...
متن کاملHomo Socialis and Homo Sapiens
The assumption that individuals are behaving rationally can, at times, usefully constrain predictions of individual and collective behavior. However, success in predicting human and group behavior will often require relaxing this assumption of rationality, instead employing evolutionary, neural, and cognitive constraints. One particularly important form of neural and cognitive constraint is tha...
متن کاملMilk availability modulates weaning in the Norway rat (Rattus norvegicus).
Two experiments were conducted to investigate the role of milk availability in the development of independent feeding and drinking in the Norway rat pup. Beginning on Day 14 postnatally, pups were exposed to different levels of milk supply by changing litter size from 8 to 4 versus 12 pups (Experiment 1) or limiting temporally the pups' access to a lactating dam to 8, 14, or 24 hr daily (Experi...
متن کاملReexamination of spectral mechanisms in the rat (Rattus norvegicus).
The spectral mechanisms of the rat were studied in electrophysiological and behavioral experiments. The photopic electroretinogram (ERG) was recorded (a) to rapidly flickering lights, (b) during the cone phase of dark adaptation, and (c) with a flicker photometric procedure. Each procedure indicated the presence of a single cone mechanism having a lambda max of about 510 nm. Increment-threshold...
متن کاملIdentification, cloning and functional characterization of novel beta-defensins in the rat (Rattus norvegicus)
BACKGROUND Beta-defensins are small cationic peptides that exhibit broad spectrum antimicrobial properties. The majority of beta-defensins identified in humans are predominantly expressed in the male reproductive tract and have roles in non-immunological processes such as sperm maturation and capacitation. Characterization of novel defensins in the male reproductive tract can lead to increased ...
