State-dependent cell-type-specific membrane potential dynamics and unitary synaptic inputs in awake mice

eLife, 2018
The cellular and synaptic mechanisms driving cell-type-specific function during various cortical network activities and behaviors are poorly understood.

Sensory Processing as a Predictor of Leisure Participation in Early Adolescents

Children, 2021
Sensory processing may be associated with adolescents’ preferences for different leisure activities. However, knowledge about how different sensory processing patterns may relate to adolescents’ participation in leisure activities is scarce.

Intrinsically Motivated Learning of Visual Motion Perception and Smooth Pursuit

, 2014
We extend the framework of efficient coding, which has been used to model the development of sensory processing in isolation, to model the development of the perception/action cycle. Our extension combines sparse coding and reinforcement learning so that

Emotional modulation of visual cortex activity: A functional nearinfrared spectroscopy study [PDF]

, 2009
Functional neuroimaging and electroencephalography reveal emotional effects in early visual cortex. Here, we used fNIRS to examine haemodynamic responses evoked by neutral, positive and negative emotional pictures, matched for brightness, contrast, hue,

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

Excitation-inhibition imbalance in medial preoptic area circuits underlies chronic stress-induced depression-like states

Nature Communications
Dysregulation of brain homeostasis is associated with neuropsychiatric conditions such as major depressive disorder. However, underlying neural-circuit mechanisms remain not well-understood.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Complementary Sensory and Associative Microcircuitry in Primary Olfactory Cortex [PDF]

, 2011
The three-layered primary olfactory (piriform) cortex is the largest component of the olfactory cortex. Sensory and intracortical inputs converge on principal cells in the anterior piriform cortex (aPC).Wecharacterize organization principles of the ...

Some investigations into non passive listening [PDF]

, 2006
Our knowledge of the function of the auditory nervous system is based upon a wealth of data obtained, for the most part, in anaesthetised animals. More recently, it has been generally acknowledged that factors such as attention profoundly modulate the ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
