Differentiation of Hebbian and homeostatic plasticity mechanisms within layer 5 visual cortex neurons.

Cortical layer 5 contains two major types of projection neuron known as IB (intrinsic bursting) cells that project sub-cortically and RS (regular spiking) cells that project between cortical areas. This study describes the plasticity properties of RS and IB cells in the mouse visual cortex during the critical period for ocular dominance plasticity. We find that RS neurons exhibit synaptic depression in response to both dark exposure (DE) and monocular deprivation (MD), and their homeostatic recovery from depression is dependent on TNF-α.

Dual-Component Structural Plasticity Mediated by αCaMKII Autophosphorylation on Basal Dendrites of Cortical Layer 2/3 Neurones.

Sensory cortex exhibits receptive field plasticity throughout life in response to changes in sensory experience and offers the experimental possibility of aligning functional changes in receptive field properties with underpinning structural changes in synapses. We looked at the effects on structural plasticity of two different patterns of whisker deprivation in male and female mice: chessboard deprivation, which causes functional plasticity; and all deprived, which does not. Using 2-photon microscopy and chronic imaging through a cranial window over the barrel cortex, we found that layer 2/3 neurones exhibit robust structural plasticity, but only in response to whisker deprivation patterns that cause functional plasticity.

Harmonic Devices: The Workhorse for Surgical Resection of Vascular Malformations.

Management of vascular malformations is multimodal with documented role of surgical resection in specific facets of this condition. Surgical resection of these lesions is technically challenging owing to diffuse and relatively ill-defined extent with involvement of multiple tissue planes limitation of access and excessive intra-operative bleeding. An observational study was conducted in 24 cases taken up for surgical resection of vascular malformations.

Open Cancellous Bone Grafting for Recalcitrant Palatal Fistula: Repurposing the Papineau Technique.

Cleft palate fistula is defined as a breakdown in the primary surgical repair of the palate resulting in oronasal communication, which can create symptomatic regurgitation for fluids/solids and affect speech, manifested by airflow escape during phonation. With the reported postoperative occurrence rate of 33-37% postfistula repair, it remains a challenging problem. The primary aim of this study was to describe our experience in the management of 7 consecutive cases of recalcitrant palatal fistula, all secondary to primary cleft palate repair.

Unusual Behavior of a Posttraumatic Scar: Craniofacial Actinomycosis.

Actinomycosis is a chronic suppurative granulomatous infection most commonly involving the cervicofacial region. Clinical diagnosis is usually difficult, and fine-needle aspiration cytology or imaging studies are usually unhelpful in diagnosing actinomycosis. Definitive diagnosis is based on the histopathological examination of a tissue biopsy.

Arterial segments as microvascular interposition grafts in venous anastomosis in digital replantations.

Depression biased non-Hebbian spike-timing-dependent synaptic plasticity in the rat subiculum.

The subiculum is a structure that forms a bridge between the hippocampus and the entorhinal cortex (EC), and plays a major role in the memory consolidation process. Here, we demonstrate spike-timing-dependent plasticity (STDP) at the proximal excitatory inputs on the subicular pyramidal neurons of juvenile rat. Causal (positive) pairing of a single EPSP with a single back-propagating action potential (bAP) after a time interval of 10 ms (+10 ms) failed to induce plasticity.
