Why do mice squeak? Toward a better understanding of defensive vocalization

iScience, 2022
Summary: Although mice mostly communicate in the ultrasonic range, they also emit audible calls. We demonstrate that mice selectively bred for high anxiety-related behavior (HAB) have a high disposition for emitting sonic calls when caught by the tail ...

Independent component analysis in spiking neurons [PDF]

, 2010
Although models based on independent component analysis (ICA) have been successful in explaining various properties of sensory coding in the cortex, it remains unclear how networks of spiking neurons using realistic plasticity rules can realize such ...

Structural plasticity of synaptic connectivity in the adult hippocampal mossy fiber projection [PDF]

, 2013
The brain has the lifelong ability to change itself based on new experiences such as learning and memory. This so called neuronal plasticity is reflected in the brain by structural and functional modifications which underlie our ability to learn ...

miR-132/212 knockout mice reveal roles for these miRNAs in regulating cortical synaptic transmission and plasticity [PDF]

, 2013
miR-132 and miR-212 are two closely related miRNAs encoded in the same intron of a small non-coding gene, which have been suggested to play roles in both immune and neuronal function.

Spike train auto-structure impacts post-synaptic firing and timing-based plasticity [PDF]

, 2011
Cortical neurons are typically driven by several thousand synapses. The precise spatiotemporal pattern formed by these inputs can modulate the response of a post-synaptic cell.

Network self-organization explains the statistics and dynamics of synaptic connection strengths in cortex [PDF]

, 2013
The information processing abilities of neural circuits arise from their synaptic connection patterns. Understanding the laws governing these connectivity patterns is essential for understanding brain function.

Unique potential of immature adult-born neurons for the remodeling of CA3 spatial maps

Cell Reports, 2023
Summary: Mammalian hippocampal circuits undergo extensive remodeling through adult neurogenesis. While this process has been widely studied, the specific contribution of adult-born granule cells (aGCs) to spatial operations in the hippocampus remains ...

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]

, 2009
Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

Diverse processing of pharmacological and natural rewards by the central amygdala

Cell Reports, 2023
Summary: The central amygdala (CeA) with its medial (CeM) and lateral (CeL) nuclei is the brain hub for processing stimuli with emotional context. CeL nucleus gives a strong inhibitory input to the CeM, and this local circuitry assigns values (positive ...

Olfactory bulb plasticity ensures proper olfaction after severe impairment in postnatal neurogenesis

Scientific Reports, 2017
The olfactory bulb (OB) neurons establish a complex network that ensures the correct processing of the olfactory inputs. Moreover, the OB presents a lifelong addition of new neurons into its existing circuitry.
