Primary Motives: Hunger and Thirst

Hunger and thirst are fundamental physiological drives crucial for maintaining homeostasis and ensuring the survival of both humans and animals. These drives are regulated through complex interactions between the brain, hormones, and sensory receptors. Hunger arises when the brain detects changes in the body's nutrient levels, including glucose, lipids, amino acids, and hormones such as ghrelin and leptin. The hypothalamus plays a central role in hunger regulation. The lateral hypothalamus acts...

Carbon fluxes in the cryosphere are hardly assessed yet but are crucial regarding climate change. Here we show a novel prototype device that captures the phototrophic potential in supraglacial environments based on laser-induced fluorescence emission (L.I.F.E.) technology offering high spectral and spatial resolution data under in situ conditions.

The vomeronasal organ (VNO) detects intraspecies chemical signals that convey social and reproductive information. We have performed Ca2+ imaging experiments using transgenic mice expressing G-CaMP2 in VNO tissue. This approach allows us to analyze the complicated response patterns of the vomeronasal neurons to large numbers of pheromone stimuli.

In this protocol we describe a method of operant learning using sensory stimuli as a reinforcer in the mouse. It requires no prior training or food restriction, and it allows the study of motivated behavior without the use of a pharmacological or natural reinforcer such as food.
FAQs
As hunger develops, an infant’s internal physiological state can increase arousal, making vocal signaling more likely. This process connects a biological need with observable behavior without treating the cry as an isolated event. Studying that connection helps psychologists examine how bodily regulation becomes part of early communication and how caregivers may respond to changing infant needs.
Crying can occur in response to more than nourishment-related needs, including discomfort or fatigue. Researchers therefore examine the broader situation surrounding the vocal signal rather than assigning one cause automatically. This comparison helps distinguish biological drives from other forms of distress and supports more careful interpretations of infant behavior in psychological research.
Feeding-related cues can contribute to increasing infant arousal as hunger develops, creating conditions in which crying becomes more likely. Considering these cues alongside the vocal behavior allows researchers to study how physiological states and environmental signals interact. The approach is relevant to early communication because infants’ needs become expressed through a combination of internal and observable processes.
Researchers can examine the cry together with the infant’s apparent hunger, feeding-related cues, and surrounding behavioral context. They can then compare that pattern with situations involving discomfort or fatigue. This contextual approach does not rely on vocal sound alone; it supports psychological analysis of how different needs may produce distinguishable signals and how caregivers evaluate them.
Research on hunger cries helps investigators examine how caregivers interpret infant signals and decide how to respond. That work contributes to understanding responsive caregiving, in which attention to an infant’s behavior is considered alongside the infant’s possible need. Findings can therefore connect early vocal communication with feeding behavior and the quality of caregiver–infant interactions.
A hunger cry creates an observable point of interaction between an infant’s biological need and a caregiver’s response. Studying these exchanges helps psychologists investigate how repeated signaling and interpretation relate to caregiver–infant relationships. The topic therefore links nourishment-related behavior with broader questions about attachment, early communication, and the development of social interaction.
