According to the two-visual-system hypothesis (Milner and Goodale 1995), after V1 the visual system splits into vision-for-action and vision-for-perception modules. Specifically, the dorsal subsystem is proposed to specialize in the visual guidance of actions, whereas the ventral subsystem in object perception and recognition. Support for the two-visual-systems hypothesis has come from monkey a...

Many signal processing systems, particularly in the multimedia and telecommunication domains, are synthesized to execute dataintensive applications: their cost related aspects — namely power consumption and chip area — are heavily influenced, if not dominated, by the data access and storage aspects. This paper presents an energy-aware memory allocation methodology. Starting from the high-level ...

It is hard to believe, but SCAN turns five in 2011 and things are going well. We received our first impact factor of 4.203, which places us #9 on the list of psychology journals and in the top 25% of all neuroscience journals. We have also become the official journal of the Social and Affective Neuroscience Society that hosts the SAN meeting each year. And we are growing. We have been running f...

Genome technologies are transforming all areas of biology, including the study of hormones, brain and behavior. Annotated reference genome assemblies are rapidly being produced for many avian species. Here we briefly review the basic concepts and tools used in genomics. We then consider how these are informing the study of avian behavioral neuroendocrinology, focusing in particular on lessons f...

Mood, motivation, attention, and arousal are behavioral states having a profound impact on cognition. Behavioral states are mediated though the peripheral nervous system and neuromodulatory systems in the brainstem. The noradrenergic nucleus locus coeruleus is activated in parallel with the autonomic system in response to biological imperatives. These responses can be spontaneous, to unexpected...

We consider the problem of designing distributed controllers to guarantee dissipativity a networked system comprised dynamically coupled subsystems. require that control synthesis is carried out locally at subsystem-level, without explicit knowledge dynamics other subsystems in network. solve this two steps. First, we provide subsystem-level analysis conditions whose feasibility sufficient syst...

Model organisms usually possess a small nervous system but nevertheless execute a large array of complex behaviors, suggesting that some neurons are likely multifunctional and may encode multiple behavioral outputs. Here, we show that the C. elegans interneuron AIY regulates two distinct behavioral outputs: locomotion speed and direction-switch by recruiting two different circuits. The "speed" ...

Behavioral assays in the undergraduate neuroscience laboratory are useful for illustrating a variety of physiological concepts. An example is homeostatic temperature regulation (thermoregulation). Many model organisms, from flies to mice, regulate internal temperatures in part by moving to suitable climates (thermotaxis). A particularly reliable method of quantifying temperature-dependent therm...

Recognizing a deadly pathogen and generating an appropriate immune reaction is essential for any organism to survive in its natural habitat. Unlike vertebrates and higher primates, invertebrates depend solely on the innate immune system to defend themselves from an attacking pathogen. In this study, we report a behavioral defense strategy observed in Drosophila larvae that helps them escape and...

We develop a biophysical model of neurosensory integration in the model organism Caenorhabditis elegans. Building on experimental findings on the neuron conductances and their resolved connectome, we posit the first full dynamic model of the neural voltage excitations that allows for a characterization of network structures which link input stimuli to neural proxies of behavioral responses. Ful...
