The role of the ventral midline thalamus in the retrieval of precise temporal memories

This study investigates the role of the ventral midline thalamus in retrieving precise temporal memories using a fixed-interval timing task in rats, showing that muscimol infusions impair timing precision.

Identifying the midline thalamus in humans in vivo

This paper introduces a method to identify the midline thalamus in humans using diffusion imaging and clustering, showing reliable classification of midline thalamic clusters in two datasets.

Reuniens transiently synchronizes memory networks at beta frequencies

This study shows that the reuniens nucleus drives beta oscillations in the prefrontal-hippocampal network during memory tasks, facilitating memory-based decision making.

Dual medial prefrontal cortex and hippocampus projecting neurons in the paraventricular nucleus of the thalamus

The paper identifies dual medial prefrontal cortex and hippocampus projecting neurons in the paraventricular nucleus of the thalamus and examines their molecular and topographic characteristics.

Dual projecting cells linking thalamic and cortical communication routes between the medial prefrontal cortex and hippocampus

The paper identifies dual projecting cells in specific brain regions that connect the medial prefrontal cortex and hippocampus via thalamic and cortical pathways in rats.

Calretinin and calbindin architecture of the midline thalamus associated with prefrontal-hippocampal circuitry

This study maps calcium binding protein expression in the midline thalamus, revealing distinct CR+ and CB+ zones and identifying dual mPFC-HC projecting cells as a unique population.

'Awake delta' and theta-rhythmic hippocampal network modes during intermittent locomotor behaviors in the rat

The paper identifies delta and theta rhythmic modes in the rat hippocampus during locomotor behaviors, showing they are functionally distinct and temporally interspersed during navigation.

Chronic Pb2+ Exposure Causes Hippocampal Network Hypersynchrony, Absence Seizures, and Sensorimotor Deficits

This study investigates the effects of chronic lead exposure on hippocampal network dynamics and behavior in rats, finding altered rhythms and impaired cognitive functions.

Medial prefrontal cortex activity reflects ordinal retrieval modes and hippocampal activity reflects temporal context retrieval modes

The paper investigates how medial prefrontal cortex and hippocampus contribute to different retrieval modes in sequence memory using fMRI.

RatHat: A self-targeting printable brain implant system

The paper introduces RatHat, a 3D-printable stereotaxic system for rat brain implants that reduces costs, training, and surgical time while improving repeatability and durability.

Prefrontal pathways provide top down control of memory for sequences of events

This study shows that prefrontal pathways regulate sequence memory retrieval in rats by controlling working memory and temporal context strategies.
