Mindfulness meditation modulates reward prediction errors in a passive conditioning task [PDF]
, 2015 Reinforcement learning models have demonstrated that phasic activity of dopamine neurons during reward expectation encodes information about the predictability of reward and cues that predict reward.

Reward responsivity and the development of nicotine dependence
, 2008 Different theories have been proposed to explain the development of nicotine dependence. Some theories suggest that nicotine has direct reinforcing properties, either positive or negative.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Commentary: New View on Treatment of Drug Dependence
Basic and Clinical Neuroscience, 2014 In the 1960s, discovery of pleasure system (defined as reward system) in the brain that may underlie drug reward and addiction encouraged many scientists to investigate the mechanisms by which drug abuse affects central nervous system function.

Neurocomputational mechanisms involved in adaptation to fluctuating intentions of others
Nature CommunicationsHumans frequently interact with agents whose intentions can fluctuate between competition and cooperation over time. It is unclear how the brain adapts to fluctuating intentions of others when the nature of the interactions (to cooperate or compete) is ...

A causal role for right temporo-parietal junction in signaling moral conflict
eLife, 2018 The right temporo-parietal junction (rTPJ) has been proposed to play a key role in guiding human altruistic behavior, but its precise functional contribution to altruism remains unclear.

Reward-based learning paradigm.
, 2016 (A) After the presentation of an Asian symbol, subjects were asked to select one of the two colours by pressing the corresponding button. The decision was followed by outcome presentation (reward or non-reward).

Bayesian cue integration as a developmental outcome of reward mediated learning [PDF]
, 2011 Average human behavior in cue combination tasks is well predicted by Bayesian inference models. As this capability is acquired over developmental timescales, the question arises, how it is learned.

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
