Effect of Tactile Stimulation on Visual Memory Performance /

By Latif, Asma . . 80p. , The human eye continuously perceives information about surroundings to be processed and stored in memory so that it can be retrieved. Environmental factors may have positive and negative effects on memory performance and human cognitive processing. Many studies have addressed the effect of auditory circumstances on spatial tasks and visual memory performance. However, only a few studies highlighted the cross-modal interaction between vision for visual cue and touch for training of same visual pattern in tactile pattern. In addition, very little research has been conducted on the effect of tactile stimulation towards memorizing visual tasks. The main objective of this study is to investigate the effect of visuo-tactile stimulation on adult memory. Sixty-two subjects participated in this behavioral study having normal and corrected to normal vision. Participants are divided into two groups and each subject goes thorough Mini mental state examination and Edinburg handedness inventory. The visual assessment task consists of different shapes along with three-digit numbers. During the memorization period, visual assessment task was displayed on computer screen and tactile stimulation was delivered on index finger of the dominant hand of the participant. The participant was provided with an evaluation sheet containing shapes only. If the shape is paired with its corresponding number, then it was be considered correct. The p-value < 0.05 in visual assessment test showed a significant effect of tactile stimulation on visual memory performance. The findings of this study concluded that participants memorized the object number pair task better in the presence of tactile stimulation as compared to control/no stimulation. One of the conclusions of our work is that combing vision and touch sense may improve cognitive ability and may be provided to people during learning and remembering visual tasks. For future recommendations, heterogenous sample along with brain response can be studied. 30cm.

Investigating the Neuroprotective Impacts of Chenodeoxycholic Acid in STZ-Induced Diabetic Neuropathy and Cognitive Impairment in BALB/c Mice /

By Bano, Maria . . 77p. , Diabetic neuropathy and cognitive impairment are common complications of diabetes, significantly affecting the lives of millions of people. Finding effective treatments for these issues remains a critical challenge. In this study, we investigated whether chenodeoxycholic acid, a naturally occurring bile acid known for its neuroprotective properties, could help alleviate these complications. We utilized a mouse model of diabetes induced by streptozotocin. The mice were categorized into three groups; a healthy control, a diabetic group and a diabetic group that receive treatment with CDCA. The diabetic mice displayed typical signs of nerve pain, anxiety-like behaviour, and memory problems. However, those treated with CDCA showed remarkable improvements in all these areas. They experienced less pain in the hot plate analgesia, exhibited reduced anxiety levels in the open field test, and demonstrated better memory and cognitive function in the test of Y-maze. Beyond behaviour, CDCA also had profound effects on the brain. It preserves the structure of neurons in critical areas like the hippocampus and cortex, which are often affected by diabetic neuropathy. At a molecular level, CDCA may reduce inflammation by decreasing nuclear factor kappa B levels, a key marker of inflammation and cell damage. The brain-derived neurotrophic factor is also increased, a protein essential for nerve growth and repair in the brain, suggesting that CDCA supports the brain’s natural ability to heal. These results provide a promising glimpse into the potential of CDCA as a treatment for diabetes-related nerve and cognitive problems. While more research is needed, the ability of CDCA to protect neurons, reduce inflammation, and improve cognitive and behavioural outcomes makes it a promising drug for future therapies aimed at improving the lives of people with diabetes. 30cm.
