Functional Brain Networks Underlying Anticipation in Motivated Behavior
… is a state of expectancy for something that will happen, and it allows us to use past learning to prepare for and make predictions about the future. Studies have shown that anticipation influences behavioral performance, learning, and memory, and studies implicate reward-related …

The Impact of Early Life Adversity on Mediodorsal Thalamic-Prefrontal Cortex Maturation
… (ELA) is known to disturb neural development and interfere with neural circuit function, causing long-lasting adverse effects on cognitive and affective behaviors. The basis for this is thought to be linked to developmental disruption of neural circuits underpinning these behaviors during a …

Multi-sensory gamma stimulation ameliorates Alzheimer's-associated pathology and improves cognition
Changes in gamma activity (30-90 Hz) have been observed in humans and animal-models of Alzheimer's disease (AD). Examining the relationship between gamma oscillations and disease pathology is a significant problem in neuroscience. Recent work using a non-invasive light flicker at 40 Hz, termed …

Decoding observational learning : a circuit level analysis of the social brain
The ability to engage in appropriate social interaction is a critical component of daily life that requires integration of multiple neural processes and can be perturbed in numerous psychiatric diseases (Adolphs et al. 2003; Frith et al. 2008). One approach to begin understanding how the brain …

Striatal Microcircuits Underlying Control of Actions
<p>The striatum is the input nucleus of basal ganglia, a group of subcortical nuclei that includes the striatum, globus pallidus, subthalamic nucleus, and substantia nigra. These brain regions have been implicated in control and coordination of motor planning and action selection. Especially, the …

Mechanisms of pain processing: spinal protein translation in the rat
The word ‘pain’ is described by the International Association for the Study of Pain (IASP) as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Shifts in pain thresholds and responsiveness are an expression of …

High-efficiency ultrasound-powered micro-LEDs for optogenetic applications
Gallium nitride (GaN) light-emitting diodes (LEDs) play the most important role in visible light applications, and more than 87% LEDs are used in indoor/outdoor lighting, automotive lighting, etc. Recent advancements in neuroscience and technology opened a new opportunity for LEDs to be used for …

Thalamocortical forward modulation in the auditory cortex
Auditory masking is a psychoacoustic phenomenon with strong physiological correlates in the central auditory system such as in the primary auditory cortex. The caveat of conventional two-tone paradigms in testing the neurophysiology of forward masking (i.e., forward suppression) is that tones are …

Feedback control of cerebellar learning
… of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. However, except in a metaphorical sense, the cerebellum, which consists of a set of interconnected …
