We mapped the receptive fields of 49 cells from primary visual cortex and 19 cells from medial superior temporal cortex in two awake monkeys. The receptive field structures we obtained lasted a mean time of 32.7 ms in primary visual cortex and 38.4 ms in medial superior temporal cortex, showing no statistical difference. This result suggests that both areas have the same time requirements for processing visual information. In primary visual cortex, 100% of cells had conformed the receptive field structure at 65 ms pre-spike, whereas in medial superior temporal cortex it occurred at 150 ms. In both areas, cells with shorter response latencies had receptive field structures with longer durations. This may indicate that cells tend to synchronize their output to other areas.

Comparative approach for abdominal wall reconstruction after ventral hernia: open versus minimally invasive surgery.
Hernia

General surgery and digestive system, Río Hortega University Hospital, Valladolid, Spain.
Introduction: The classic open ventral hernia repair provides excellent results in recurrences. However, wound complications are the Achilles heel for a good overall clinical outcome. Laparoscopic surgery is in general associated with less pain, better esthetic results, faster recovery, and lower incidence of wound complications.

Purpose: To describe the clinical characteristics of glaucoma-related adverse events (GRAE) after pediatric cataract surgery. More importantly, to identify the factors associated with the time of GRAE onset and the preferred anti-glaucomatous surgical procedure for this disease.
Methods: Hospitalized medical records of patients who developed GRAE, which include glaucoma and glaucoma suspect, after pediatric cataract surgery (surgical age ≤ 14 years) between 1994 and 2021 were retrospectively reviewed.
Biomaterial-based strategies for primary human corneal endothelial cells for therapeutic applications: from cell expansion to transplantable carrier.

The treatment of corneal blindness due to corneal diseases and injuries often requires the transplantation of healthy cadaveric corneal endothelial graft tissue to restore corneal clarity and visual function. However, the limited availability of donor corneas poses a significant challenge in meeting the demand for corneal transplantation. As a result, there is a growing interest in developing strategies alleviate this unmet need, and one of the postulated approaches is to isolate and expand primary human corneal endothelial cells (HCECs) for use in cell therapy.

Objective: To perform a systematic literature review analyzing visual outcomes of immediate, early, and delayed vitrectomy in the treatment of acute endophthalmitis after intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections.
Methods: We conducted a literature search using the Ovid Medline, Embase.com, and Web of Science databases, and relevant articles were selected from original English papers published from 2005 to 2021.
Challenges in the management of visual and tactile hallucinations in elderly people.
World J Psychiatry
January 2025
Division of Geriatric Psychiatry, Department of Psychiatry, Changhua Christian Hospital, Changhua 500, Taiwan.
This letter provides a concise review of the pertinent literature on visual and tactile hallucinations in elderly patients. The discussion addresses differential diagnoses and potential underlying mechanisms, as well as the psychopathology associated with tactile hallucinations, and emphasizes the necessity for investigation into the possibility of coexisting delusional infestation (parasitosis). These symptoms frequently manifest in patients with primary psychotic disorders, organic mental disorders, and substance use disorders.
