Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Normalizing population receptive fields

Proceedings of the National Academy of Sciences, 2021
The visual system is spatially organized. Each neuron responds to stimulation at a specific region in the visual field—its “receptive field”—and is largely unresponsive to stimulation elsewhere. For decades, electrophysiologists have characterized the receptive fields of neurons with invasive recordings (1, 2), providing the foundation for visual ...

Visual receptive field organization

Current Opinion in Neurobiology, 2005
Increasingly systematic approaches to quantifying receptive fields in primary visual cortex, combined with inspired ideas about functional circuitry, non-linearities, and visual stimuli, are bringing new interest to classical problems. This includes the distinction and hierarchy between simple and complex cells, the mechanisms underlying the receptive ...

Anæsthesia and Receptive Fields

Nature, 1965
Hubel and Wiesel1,2 have described the responses of cells in the cat's visual cortex to precise stimulation of the retina. They say: “A comparison of visual responses in the anaesthetized animal with those in the unansesthetized unrestrained preparation1 shows that the main differences lie in the frequency and firing patterns of maintained activity and

Auditory Cortical Spatial Receptive Fields

Audiology and Neurotology, 2001
Neurons in the primary auditory cortex (AI) of anesthetized cats were studied for their sensitivity to directions of transient sounds in virtual acoustic space under a variety of conditions. An effective transient sound evokes a single spike or short burst of spikes with a precisely timed onset.
