The deep layers of the entorhinal cortex are important for spatial cognition, as well as
memory storage, consolidation and retrieval. A long-standing hypothesis is that deep-layer …

Spatial learning requires estimates of location that may be obtained by path integration or
from positional cues. Grid and other spatial firing patterns of neurons in the superficial medial …

The potential energy surface associated with internal rotation of a pair of geminal functional
groups was studied using electron structure calculations. The functional groups were …

Neurons in the retrohippocampal cortices play crucial roles in spatial memory. Many
retrohippocampal neurons have firing fields that are selectively active at specific locations, with …

The conformational space of β-turns of Ala-Gly dipeptide is analyzed theoretically using
quantum mechanical methods. A number of potential minima are obtained and characterized. …

Questions about information encoded by the brain demand statistical frameworks for inferring
relationships between neural firing and features of the world. The landmark discovery of …

C radicals are typically trigonal planar and thus achiral, regardless of whether they originate
from a chiral or an achiral C-atom (eg, C–H + • OH → C• + H 2 O). Oxidative stress could …

Electron structure calculations on N-acetyl asparagine N-methylamide were performed to
identify the global minimum from which radicals were formed after H-abstraction by the OH …

Asp radical has enantiomeric d and l form, due to axis chirality. This pair of degenerate minima
is occurring on a single 4D-Ramachandran Potential Energy Hyper Surface (PEHS). The …

Spatial computations are thought to be processed in the hippocampal-entorhinal network
and involve neurons with spatially selective firing properties. The deep medial entorhinal …
