Factors Regulating Cerebellar Granule Neuron Progenitor Proliferation
Cerebella granule neuron progenitors (CGNPs) give rise to a homogenous group of neurons called the cerebellar granule neurons in the developing cerebellum (a hindbrain structure classically associated with fine motor ... -
How does familiarity change visual object representations ?
Familiarity with something implies having a close acquaintance with that item, generally acquired over a period of time. Apart from single items, we have experienced getting familiar with a pair of items (like a mouse and ... -
Investigating mechanisms underlying astrocytic involvement in depressive-like behavior and antidepressant action
Major Depressive disorder (MDD) is a complex, multifactorial psychiatric illness which affects over 20% of the population worldwide. Despite its prevalence, our understanding of its pathophysiology is severely limited, ... -
Investigating the neural basis of spatial attentional components with probabilistic and reward cueing
We are constantly inundated with an abundance of sensory information. “Attention” enables the selection of relevant information and filtering out irrelevant information, to guide adaptive behavior. While attention can be ... -
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, ... -
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 ... -
Mechanisms of Dopaminergic Neurodegeneration in Parkinson's Disease
(2018-07-18)Parkinson’s disease (PD) is a debilitating movement disorder. The cardinal symptoms of PD are bradykinesia, resting tremors and rigidity. PD is characterized by degeneration of dopaminergic neurons of A9 region, substantia ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
PSD95 as a biophysical modulator of synaptic communication
PSD95 is a core scaffold protein of the postsynaptic density (PSD) at excitatory synapses and a member of the MAGUK family, where it plays a central role in organizing glutamate receptors, ion channels, and signalling ... -
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 ... -
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). ... -
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 ... -
The Role of Cytoskeletal Morphology in the Nanoorganization of Synapse
(2018-01-10)Synapse is the fundamental unit of synaptic transmission. Learning, memory and neurodegenerative diseases of the brain are attributed to the maintenance and alteration in synaptic connections. The efficiency for synaptic ... -
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 ... -
Shared and distinct mechanisms of saccade preparation, external and internal attention
Everyday activities – like reading an email, watching a football match, scrolling through social media, or window-shopping – all involve quickly scanning complex visual scenes using rapid eye movements called “saccades.” ... -
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, ...
