The Key Role of 3D TEE in Assessing the Morphology of Degenerative Mitral Valve Regurgitation.

Two-dimensional transthoracic echocardiography (2D TTE) and two-dimensional transesophageal echocardiography (2D TEE) are regarded as the main imaging techniques for the assessment of degenerative mitral valve regurgitation (DMVR). However, describing the complex morphology of DMVR with 2D TTE and 2D TEE remains at the very least challenging. Three-dimensional (3D) TEE is an ideal technique for illustrating the extremely variable morphology of DMVR, providing images of unparalleled quality in terms of anatomical detail.

Connectome-driven neural inventory of a complete visual system.

Vision provides animals with detailed information about their surroundings, conveying diverse features such as color, form, and movement across the visual scene. Computing these parallel spatial features requires a large and diverse network of neurons, such that in animals as distant as flies and humans, visual regions comprise half the brain's volume. These visual brain regions often reveal remarkable structure-function relationships, with neurons organized along spatial maps with shapes that directly relate to their roles in visual processing.

Silence, Second Skin, and the Unrepresented.

Using the concepts of and , this paper explores the idea that a patient's silence in the session may function at multiple levels of psychic and relational organization, and-by virtue of its somatically experienced qualities and the special countertransference states these may elicit-might serve as a vehicle for movement between levels. It can thus be fruitfully approached as a potential portal for access to, and creative transformation of, unrepresented experience.
