Differential Regulation of Calcium Dependent Phase Separation and Modular Assembly of Sap97/Hdlg Enriched Molecular Complexes
Recent studies over a few decades have changed the perspective of the molecular architecture of functional zones within synapses and other cell junctions. Observations in the last decade confirm Post Synaptic Density as ... -
Effect of Stimulus Normalization and Visual Attention at multiple scales of Neural Integration
The effect of visual attention on neural signals has been extensively studied using various techniques such as macaque neurophysiology and human electro/magneto encephalogram (EEG/MEG). Depending on the technique, different ... -
Role of calcium sensors in differential alignment of synaptic nanomachinery during neurotransmission
Some of the brain's most remarkable feats such as learning and memory, are thought to emerge from elementary properties of chemical synapses. The distinctive feature of these synapses is that the action potential in the ... -
Computational mechanisms underlying eye-head coordination
Gaze or eye-head coordination is an ethologically and physiologically important process that directs the visual system to objects of interest. Due to its relative simplicity, it is an ideal system to study multi-effector ... -
Optical and behavioural tools to investigate the neural correlates of learning and memory
Events in our everyday life are encoded as memories that can be consciously recollected and remembered, although our ability to retrieve the specific details associated with these events diminish with time. Such losses ... -
Use of Human Induced Pluripotent Stem Cells as a Model to Study Primary Microcephaly
The aim of this study was to use human induced pluripotent stem cells (hiPSC) to understand key steps of neuronal differentiation and to model the human brain developmental disorder, primary microcephaly (MCPH). MCPH is a ... -
Structural Correlates of Related Contextual Learning in Retrosplenial Cortex
The discovery of dendritic spines by Santiago Ramón y Cajal is one of the most important chapters in the history of neuroscience. Apart from establishing the neuron doctrine, it presented dendritic spines as the information ... -
Neural Correlates and Behavioral Underpinnings of Remote Memories during Systems Consolidation
Remote retrieval of declarative memories has been under investigation for a long time. After acquisition, long-term encoding of memories happens through crosstalk across multiple brain regions. Through systems consolidation, ... -
Estimation of the spatial spread of brain signals at multiple scales
Spatial spread of a particular brain signal can be defined as the area of the cortical tissue around the recording electrode that contributes to the electrical activity recorded by the electrode. More specifically, ... -
Aβ42-mediated dendritic spine loss in an in-vitro model of Alzheimer’s disease
The results from this study establish the molecular mechanism underlying the Aβ42-mediated dendritic spine loss observed in the APP/PS1 mouse model of AD. Further, this study highlights the role of Aβ42 in altering the ... -
Regulation of Lateral Mobility of Amyloid Precursor Protein by an Alzheimer’s Disease Risk Gene: Picalm
Amyloid Precursor Protein (APP) is implicated in several functions in neurons, but the altered processing of APP in synapses holds a key to understanding the onset of the molecular progression of Alzheimer’s Disease (AD). ... -
Novel Therapeutic Targets for Alzheimer’s Disease
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by impaired memory and other cognitive deficits. Even though the genes associated with familial AD were discovered more than three decades ... -
SRF regulates the generation of neuroprotective astrocytes in the brain
In response to injuries, infections or in neurodegenerative disorders, astrocytes get activated to become reactive. This phenomenon is called astrogliosis and is marked by a spectrum of changes which encompasses structural, ... -
Structure-Function Analysis of Focal Adhesion Protein Vinculin in Neocortical Axon Growth and Development
Axon growth and extension are dependent on the interaction of neurons with extracellular matrix (ECM). The interaction between cells and ECM is known as focal adhesion (FA). Vinculin is one the major proteins of FA complex ... -
Super-Resolution Imaging Reveals Localization and Regulation of Nanoscale Machinery Involved in the Amyloidogenic Pathway
Amyloid Precursor Protein (APP) is a key player in Alzheimer’s disease (AD). Despite intuitive insights into differential proteolysis of APP, there is a little understanding of how the amyloidogenic machinery is distributed ... -
Is Spatial Map Shaped by Environmental Determinants?
Humans and other animals form internal mental maps of the outer world in order to navigate. Hippocampal place cells and grid cells in MEC (medial entorhinal cortex) are the key components of this navigation system. However, ... -
Computational Mechanisms Underlying the Voluntary Control of Reach Movement Planning and Execution
In everyday life we make a variety of reaching movements. Most of these reaching movements have a clear objective of bringing the hand to the spatial location of the object of interest. Although we typically do not explicitly ... -
Maternal Immune Activation Perturbs Gene Expression in the Embryonic Brain Leading to Autism Spectrum Disorders
Autism Spectrum Disorders (ASD) constitutes a spectrum of developmental disorders that share common phenotypes of social and communication deficits and repetitive behaviours. ASDs have many possible underlying causes ... -
Neural Mechanisms underlying the planning of sequential saccades
Saccades are rapid eye movements that we continually make (about 2-3 times per second) to look around and scan our visual environment. Though we effortlessly execute saccadic eye movements all the time, they are not just ...
