DOI: 10.1002/cne.25462
Abstract: The current study aimed to reveal in detail patterns of intrahippocampal connectivity in homing pigeons (Columba livia). In light of recent physiological evidence suggesting differences between dorsomedial and ventrolateral hippocampal regions and a hitherto unknown… read more here.

DOI: 10.1002/glia.24175
Abstract: Traumatic brain injury (TBI) can be progressive and can lead to the development of a long-term complication termed chronic traumatic encephalopathy. The mechanisms underlying the progressive changes are still unknown; however, studies have suggested that… read more here.

DOI: 10.1002/hbm.26319
Abstract: The hippocampus is known to be critically involved in associative memory formation. However, the role of the hippocampus during the learning of associative memory is still controversial; while the hippocampus is considered to play a… read more here.

DOI: 10.1002/hipo.22706
Abstract: The hippocampus is subjected to diurnal/circadian rhythms on both the morphological and molecular levels. Certain aspects of cell proliferation in the adult hippocampus are regulated by melatonin and accompanied by apoptosis to ensure proper tissue… read more here.

DOI: 10.1002/hipo.22752
Abstract: The pilocarpine‐induced status epilepticus rodent model has been commonly used to analyze the mechanisms of human temporal lobe epilepsy. Recent studies using this model have demonstrated that epileptic seizures lead to increased adult neurogenesis of… read more here.

DOI: 10.1002/hipo.22825
Abstract: The hippocampus is functionally differentiated along its longitudinal axis, with the dorsal and ventral segments preferentially involved in cognitive and emotional processing, respectively. Serotonergic modulation of hippocampal function has been extensively studied, but its relation… read more here.

DOI: 10.1002/hipo.23023
Abstract: Despite tremendous progress, the neural circuit dynamics underlying hippocampal mnemonic processing remain poorly understood. We propose a new model for hippocampal function—the simulation‐selection model—based on recent experimental findings and neuroecological considerations. Under this model, the… read more here.

DOI: 10.1002/hipo.23050
Abstract: The hippocampus supports flexible decision‐making through memory integration: bridging across episodes and inferring associations between stimuli that were never presented together (‘associative inference’). A pre‐requisite for memory integration is flexible representations of the relationships between… read more here.

Chronic in vivo optogenetic stimulation modulates neuronal excitability, spine morphology, and Hebbian plasticity in the mouse hippocampus

DOI: 10.1002/hipo.23080
Abstract: Prolonged increases in excitation can trigger cell‐wide homeostatic responses in neurons, altering membrane channels, promoting morphological changes, and ultimately reducing synaptic weights. However, how synaptic downscaling interacts with classical forms of Hebbian plasticity is still… read more here.
