We have been super busy!

New Publication – 27-11-2020

We published a new paper on impairing effects of transcranial direct current stimulation (tDCS) on memory performance. These results suggest that for complex task, tDCS is ineffective at improving learning speed and potentially detrimental to long-term retention when employed during encoding. This serves to highlight the complex nature of brain stimulation, providing a greater understanding of its limitations and drawbacks.

Reduction of Stroke Admissions – 26-11-2020

We published an article showing a reverse correlation between increased number of COVID-19 cases and stroke admissions, in particular between February 2020 and June 2020. This article is published in collaboration with Fern Rodgers, my fantastic research assistant at UCL. To read the full article please refer to this page.

Why working out your brain is just as important as your body – 18-09-2020

I commented on a news post published in the Metro by Vicki-Marie Cossar. In this piece I talked about importance of physical exercise and cognitive engagement in cognitive health. Importantly I talked about different mechanisms that contribute in this process. You can see the full post here (PDF, HTML).

BCEM Conference – 20-05-2020

Brain. Cognition. Emotion. Music (BCEM) Conference happened online with more than 600 attendees from across the world In this conference we explored the effects of music on people and the human connection with music, bringing in research and expertise from a number of fields including psychology, musicology, and ethology. Despite original plans being interrupted by Covid-19, we moved the conference online with great success, seeing over 600 attendees.


New Publication – 15-01-2020

We published a new paper looking at effect of electrical brain stimulation on visual perception. We showed that stimulation of the occipital area modulates visual perception, but stimulation of the frontal area does not. The spatial and frequency specificity of our results have implications for research on the functional organization of perception

Which of the three patterns on the bottom match the pattern on the top? We showed that electrical stimulation of the occipital area helps you make this judgement faster.

New Publication – 19-12-2019

We published a new paper looking at effect of physical exercise on memory. In this study we showed that moderate-intensity exercise can benefit memory significantly better than low- and high-intensity exercise. We ran this study across three years with one PhD, two MSc and two BSc students.

This review discusses three main factors that contribute to memory enhancement – 1) emotion, 2) targeted memory reactivation, and 3) neural reinstatement. Here we suggest methodological factors to consider in future studies, and discuss several unanswered questions that should be pursued in order to clarify selective memory enhancement.

Collaboration with NHS – 28-05-2019

We organised a Research Day with our colleagues at Kent and Medway NHS and Social Care Partnership Trust (KMPT) as well as Canterbury Christ Church (CCC). It was a day full of discussions and events with more than 100 attendees.

This Kent Research Day aimed to improve research in our region for everyone involved – service users, KMPT staff and academics. The morning talks brought together speakers from organisations around Kent to address (1) how to do research on a practical level, and (2) how we can work together to get research ideas past the thinking stage and produce Kent home-grown research. The afternoon collaboration workshops was a chance to break off into topics of interest, to develop research ideas and form ‘research networks’ for the future.

In a study we investigated brain activity during navigation in well-known and familiar environments. Posterior hippocampal activity tracked the distance to the goal in the newly learned campus, as well as in familiar environments when the future route contained many turns. By contrast retrosplenial cortex only tracked the distance to the goal in the familiar campus.

In a study we investigated subjective perception of travel time and distance in an environment in which certain locations in the world can only be reached by circumnavigating obstacles. Our results showed all travel times are underestimated and all distances are overestimated. Moreover, when circumnavigation is required, travel times are further compressed and distances are further expanded.

As you might know, last day of February was Pancake Day (Shrove Tuesday). With that excuse we had a pancake night on Monday (as Tuesday was Fern’s birthday).
