Laminating the hippocampus [PDF]
Nature Reviews Neuroscience, 2006 Lamination of neurons and fibre projections is a fundamental organizational principle of the mammalian cerebral cortex. A laminated organization is likely to be essential for cortical function, as studies in mutant mice have revealed causal relationships between lamination defects and functional deficits.

Hippocampus, 2017
AbstractThe concept of cognitive map has been proposed as a way to organize our experiences and guide behavior across all domains of cognition. The hippocampus has been identified as the neural substrate supporting cognitive maps for navigating physical space. Recent evidence is broadening the role of the hippocampus into mapping other manner of spaces.

Current Pain and Headache Reports, 2018
The hippocampus is involved in pain processing, pain-related attention and anxiety, and stress response. The present review compiles the present knowledge of hippocampal volume, activity, and connectivity regarding migraine.For hippocampal volume, a longitudinal study discovered decreased volume in newly diagnosed migraine patients after 1 year.

Long-term memory impairments have great medical significance and a considerable health and economic burden. Understanding their cognitive and neuroanatomical underpinnings is of crucial importance. Severe amnesia is usually observed following bilateral hippocampal pathology.

Medical Hypotheses, 2019
To date, there is no clear evidence for memory formation. In this article, we provide a framework to understand how memory is formed. The information collected by sensory organs is converted to a digital current that enters the presynaptic neuron through axonal conductance. Digital waves are converted to analog waves in the synapses. The analog current

Reviews in the Neurosciences, 2013
An important assumption concerning the physiology of consciousness is that all varieties of conscious experience are closely related to each other and, hence, are subserved by the same neural mechanism. There are several considerations that lead us to implicate the hippocampus in the generation of conscious perception and, ultimately, of conscious ...

Is the avian hippocampus a functional homologue of the mammalian hippocampus?
Neuroscience & Biobehavioral Reviews, 2000The effects of hippocampal lesions on the processing and retention of visual and spatial information in birds and mammals is reviewed. Both birds and mammals with damage to the hippocampus are severely impaired on a variety of spatial tasks, such as navigation, maze learning, and the retention of spatial information. In contrast, both birds and mammals

Abstract It seems that the hippocampus is concerned in human beings with imprinting and early recall of memories. Experiments on animals give confusing results but can be reconciled with this view. A theory is put forward to explain how the hippocampus may perform this function.

Hippocampus, time, and memory.
Behavioral Neuroscience, 1984Five experiments were conducted to determine the effects of hippocampal damage on timing and the memory for temporal events. In Experiments 1-3, rats were trained to discriminate between auditory signals that differed in both duration (2 or 8 s) and rate (2 or 16 cycles/s).

The hippocampus and neurotransplantation
Neuroscience and Behavioral Physiology, 2005The present article is a review of our own results from histological and electron microscopic studies of hippocampal neurotransplants with different levels of integration with recipient brains. A model providing complete isolation from the brain was obtained using transplants developing in the anterior chamber of the eye.
