Chemosensory navigation in disease vector mosquito larvae
Mosquitoes spread deadly diseases that kill millions of people every year. Understanding mosquito physiology and behavior at all life stages is vital for public health and disease prevention. In these series of chapters ... -
From Genetics to Behavior, the Dynamics and Mechanisms of Adult Neurogenesis in a Sensorimotor Circuit
The most defining attribute of the nervous system is that it shows extensive plasticity of structure and function that allows animals to adjust their behavior, physiology, and morphology to changes in their environment. ... -
Functions of the SLC36 transporter Pathetic in growth control of Drosophila sensory neurons
Dendrites exhibit enormous diversity in form and can differ in size by several orders of magnitude even in a single animal. However, whether neurons with large dendrite arbors have specialized mechanisms to support their ... -
Microtubule Dynamics in Neuronal Morphogenesis
Microtubules in neurons provide structural stability, and also provide a transport route for cellular cargo carried by motor proteins. Exactly how microtubules are organized and maintained in neurons is not clear, but ... -
Molecular and Biophysiological Differences in Neuronal Innexin Gap Junctions Likely Underlie Unique Circuit Behaviors in Hydra vulgaris
Connexins, in vertebrates, and Innexins, in invertebrates, are non-homologous gene families that are both known to form functionally similar channels. Connexins have been well characterized both functionally and molecularly ... -
Multiple zebrafish atoh1 genes specify a diversity of neuronal types in the zebrafish hindbrain
The basic Helix-Loop-Helix transcription factor, Atoh1, is known to specify several neuronal subtypes including one of most abundant cell types in the vertebrate brain, cerebellar granule neurons. The function of atoh1 in ... -
Neural Circuits Underlying Circadian Photoreception
Light is an important environmental signal that affects many different aspects of physiology and behavior to allow organisms to both predict and respond to their surroundings. For example, light influences the timing of ... -
Noradrenergic Modulation in the Mouse Auditory Midbrain
The orchestration of diffuse actions is essential for the efficient functioning and behavior of animals. Information processing across the central nervous system is regulated and coordinated by small groups of neurons in ... -
Regulation of dendrite growth, placement, and patterning in Drosophila melanogaster class 4 dendrite arborization neurons
The directional flow of information in neurons depends on compartmentalization: dendrites receive inputs whereas axons transmit them. Axons and dendrites likewise contain structurally and functionally distinct subcompartments. ... -
Role of epithelial cells in detection and response to sensory stimuli in Drosophila
Interactions between cell types plays an important role in shaping the morphology and function of those cells. One powerful example is in the peripheral nervous system, where sensory neurons coordinate with epidermal ... -
The role of wing mechanosensory feedback in insect flight control
Flying insects rapidly stabilize after perturbations using multiple sensory modalities (e.g., vision mechanoreception, olfaction) for active control. Mechanoreceptors’ direct coupling of sensory structure to the environment, ... -
Sleepless in Seattle: How Human Sleep Patterns Kept Me Up At Night
There is a sleep deprivation epidemic in the United States, particularly amongst teens and young adults. During puberty, teens undergo biological changes to their circadian system that leads to a preference for later ... -
Visual learning and processing in the honeybee, Apis mellifera
The honeybee, Apis mellifera, is well-known for her crucial role in crops pollination and for producing an highly-appreciated food, the honey. Indeed, the first historical record of bee-keeping dates from the Mesolithic ...
