Circuits and mechanisms for surround modulation in visual cortex

…, L Nurminen, F Federer, S Merlin… - Annual review of …, 2017 - annualreviews.org
Surround modulation (SM) is a fundamental property of sensory neurons in many species and
sensory modalities. SM is the ability of stimuli in the surround of a neuron's receptive field (…

[HTML][HTML] Top-down feedback controls spatial summation and response amplitude in primate visual cortex

L Nurminen, S Merlin, M Bijanzadeh, F Federer… - Nature …, 2018 - nature.com
Sensory information travels along feedforward connections through a hierarchy of cortical
areas, which, in turn, send feedback connections to lower-order areas. Feedback has been …

[HTML][HTML] Ten_m3 regulates eye-specific patterning in the mammalian visual pathway and is required for binocular vision

CA Leamey, S Merlin, P Lattouf, A Sawatari, X Zhou… - PLoS …, 2007 - journals.plos.org
Binocular vision requires an exquisite matching of projections from each eye to form a cohesive
representation of the visual world. Eye-specific inputs are anatomically segregated, but …

Hippocampus–prefrontal coupling regulates recognition memory for novelty discrimination

…, PG Stratton, CCY Lee, L Xu, S Merlin… - Journal of …, 2021 - Soc Neuroscience
Recognition memory provides the ability to distinguish familiar from novel objects and places,
and is important for recording and updating events to guide appropriate behavior. The …

[PDF][PDF] Distinct laminar processing of local and global context in primate primary visual cortex

M Bijanzadeh, L Nurminen, S Merlin, AM Clark… - Neuron, 2018 - cell.com
Visual perception is affected by spatial context. In visual cortex, neuronal responses to stimuli
inside the receptive field (RF) are suppressed by stimuli in the RF surround. To understand …

[HTML][HTML] A direct interareal feedback-to-feedforward circuit in primate visual cortex

C Siu, J Balsor, S Merlin, F Federer… - Nature …, 2021 - nature.com
The mammalian sensory neocortex consists of hierarchically organized areas reciprocally
connected via feedforward (FF) and feedback (FB) circuits. Several theories of hierarchical …

Age-specific retinal and cerebral immunodetection of amyloid-β plaques and oligomers in a rodent model of Alzheimer's disease

U Habiba, S Merlin, JKH Lim… - Journal of …, 2020 - content.iospress.com
Background: Amyloid-β soluble oligomers (Aβo) are believed to be the cause of the
pathophysiology underlying Alzheimer’s disease (AD) and are normally detected some two decades …

[PDF][PDF] Orientation preference maps in Microcebus murinus reveal size-invariant design principles in primate visual cortex

…, JDF Weidinger, M Prsa, M Schottdorf, S Merlin… - Current Biology, 2021 - cell.com
Orientation preference maps (OPMs) are a prominent feature of primary visual cortex (V1)
organization in many primates and carnivores. In rodents, neurons are not organized in OPMs …

[HTML][HTML] Immp2l knockdown in male mice increases stimulus-driven instrumental behaviour but does not alter goal-directed learning or neuron density in cortico …

BK Leung, S Merlin, AK Walker, AJ Lawther… - Behavioural Brain …, 2023 - Elsevier
Cortico-striatal neurocircuits mediate goal-directed and habitual actions which are necessary
for adaptive behaviour. It has recently been proposed that some of the core symptoms of …

Deletion of Ten-m3 induces the formation of eye dominance domains in mouse visual cortex

S Merlin, S Horng, LR Marotte, M Sur… - Cerebral …, 2013 - academic.oup.com
The visual system is characterized by precise retinotopic mapping of each eye, together with
exquisitely matched binocular projections. In many species, the inputs that represent the …
