The Impact of the Environment for Shaping Food Intake. Does it Contribute to Obesity?
… intake habits reveals a propensity for us to let external cues and signals determine the amount of food eaten rather than the internal biological signals of satiety. These external determinants can range from the lighting in the restaurant to the size of the bowl to the number of people with which …

Building an Allocentric Traveling-Direction Signal Via Vector Computation
… that is, the traveling angle in reference to external cues. Past work has identified neurons in Drosophila and mammals that track an animal's heading angle referenced to external cues (e.g., head-direction cells), but this new signal illuminates how the sense of space is properly updated when …

The LHRH pulse generator in the New Zealand white rabbit
… as the influence of the following internal and external cues which regulate the LHRH pulse generator: steroids, sexual stimuli, and seasonal influences.

How cue-dependent is memory?: Internal reinstatement and cueing effects in recognition and source memory
… context reinstatement in masking the effects of external context cues on recognition and source memory. Participants studied words paired with pictures of male and female faces. Following the study phase, participants completed either a source test in which they decided whether each test word was …

The effects of incubation manipulation on prolactin secretion in Adélie penguins (Pygoscelis adeliae)
… and the environment in which the birds breed. External cues (eggs and chicks) may promote or maintain the secretion of prolactin. The pattern of prolactin secretion may also be under the control of an internal cycle of timed events associated with the reproductive cycle. One way to gain …

Investigation of two-component signaling systems in Pseudomonas aeruginosa and their roles in the mucus barrier
… of a membrane-bound histidine kinase that senses external cues signals, and a cognate cytoplasmic response regulator that triggers changes in gene expression. The importance of these systems is highlighted by the fact that they have been identified in the vast majority of sequenced bacteria. …

The effects of contextual cues on consumers' perceptions of comparative price advertisements
… study examines the joint effects of extrinsic cues, such as comparative price (regular price /sale price), brand name, country-of-manufacture, and retailer name, on a consumer's perception of a product's price and quality. In examining the effects of advertising contextual cues, this study …

Orienting of willed temporal attention: an EEG study
… In most studies on temporal orienting external cues have been used to direct participants' attention. However, in everyday life, we also make internal choices, without external cues, of when to orient our attention. Recent studies in visual-spatial attention developed a paradigm aiming …

THE INTERPLAY BETWEEN ETHYLENE SIGNALING AND FLAVONOL ANTIOXIDANTS IN MODULATING STOMATAL MOVEMENT AND ROOT ARCHITECTURE
… are continuously exposed to a diverse array of external stimuli, threatening their ability to survive, grow, and reproduce. To cope with fluctuating environments, plant growth and development are regulated by elegant internal signaling pathways that connect external cues with growth response. …

Programming and reprogramming cellular identity
… (miRNAs). Additionally, cells must respond to external cues, and signal transduction pathways converge on gene regulatory machinery to shape cellular identity. The work presented here focuses on the mechanisms by which transcription factors, chromatin regulators, miRNAs and signal transduction …

Quantitative Single-Cell Imaging Reveals Insulation of Morphogenic Signal Transduction
How cells integrate external cues in order to make behavioral decisions is a central problem of cell biology. In development and in tissue-homeostasis, cell-fate decisions are made by the integration of multiple morphogenic signals, but how cells convert such combinations of signals into distinct …

Study of cell-cell communication using 3D living cell microarrays
… from within; it is also guided by a myriad of external cues. If cells are removed from their natural environment, apart from the microenvironment and social context they are accustomed to, it is difficult to study their behavior in any meaningful way. To that end, I describe a method for using …

Likely Old or Likely New? Taking Memory Advice During Recognition Decisions
We examined the influence of external recommendations on recognition memory decisions. In contrast to prior literature that primarily focuses on the negative impacts of external influences during memory judgments, we investigated whether participants can capitalize on explicit reliable …

Non-Photic Mechanisms of Entrainment In Bmal1 Deficient Conditions
… diseases, and various types of cancer. Various external cues that have become a part of the modern times such as electricity, shift -work, rapid travel across various time zones, easier access to nutritionally unbalanced food items, and various rigid social demands have deleterious effects on …

Dopamine and reward : effects of dopamine antagonist drugs on operant and consummatory behaviours

Learning temporal representations in cortical networks through reward dependent expression of synaptic plasticity
… and reliably represent durations specified by external cues during a training period. Analysis of a non-linear spiking neuron model is accomplished using a mean-field approach. The form of temporal learning described has specific implications that can be confirmed experimentally and these …

Maze Learning and Recall in Weakly Electric Fish, Mormyrus rume proboscirostris Boulenger 1898 (Teleostei, Mormyridae): Sensory Bases
… similar across groups suggesting independence of external input. Allowing trained fish to start from a novel location provided evidence for path integration and dead reckoning, but not cognitive mapping.</p> <p>When the arena provided additional visual or electric landmarks during acquisition, …

Mathematical Modeling of Circadian Rhythms in Drosophila melanogaster
… that is, they persist in the absence of external cues (in an environment of constant light intensity, temperature, etc.). Secondly, they are temperature compensated, that is, the nearly 24 hour period of the endogenous oscillator is remarkably independent of ambient temperature. Finally, …
