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 ...
Role of Mint family of Proteins in the nanoscale localization and real-time retention of surface Amyloid Precursor
Amyloid beta, a key determinant in the pathology of Alzheimer's disease (AD), is formed by the sequential proteolysis of Amyloid Precursor Protein (APP) by β-and γ-secretase. Evidence over the last few decades indicates ...
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 ...
Characterization of Neuroprotective Reactive Astrocytes in the Aging Mammalian Brain
The brain manifests cognitive deficits in aging and becomes more vulnerable to neurodegeneration. Astrocytes play several critical roles in the brain, including synapse formation, maturation, elimination, and synaptic ...
Parietal and prefrontal control of distinct components of attention
In this thesis, we investigate behavioural mechanisms and neural substrates of distinct components of endogenous spatial attention. Endogenous attention facilitates neural processing of the selected stimulus through one ...
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 ...
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 ...
Astrocytes regulate oligodendrocyte development and myelination in the mammalian brain
Oligodendrocytes (OLs), a type of glial cell, are the main myelinating cells of the mammalian central nervous system (CNS), enabling efficient saltatory mode of nerve conduction. On the other hand, astrocytes, another glial ...
Qualitative similarities and differences between monkey and human visual perception
Animal models play a crucial role in helping neuroscientists unravel the computations supporting behaviour at the resolution of a single neuron in the brain. In vision science, the macaque monkey is the pre-eminent model ...
Decoding of Attention and Behavioral State Using Local Field Potentials
Visual attention has been shown to modulate perceptual behavior and neuronal activity. Early psychophysical studies on attention showed that the subjects detected a target presented at the attended location better (i.e., ...
