MRC Cognition and Brain Sciences UnitWhen kids struggle in school, one of the first steps toward getting them help is often labelling their difficulties with a formal diagnosis, like attention deficit and hyperactivity disorder (ADHD), autism, or dyslexia. But few children experience symptoms that fit neatly a single category – a complication that has hindered efforts to uncover the origin […]
Auditory-inspired algorithm to improve speech perception and reduce power consumption
Worldwide over 800,000 people with severe-to-profound hearing loss use a cochlear implant (CI) to perceive sound. CIs can be used by babies, who are born deaf, after just a few months up to the elderly who lost their hearing later in life. Despite ongoing research efforts, speech perception in noisy environments remains a major problem […]
Causes and individual effects for speech perception difficulties with cochlear implants
Cochlear implants (CIs) are neuroprostheses that can provide good speech perception in quiet listening situations, but often fail to do so in environments with interfering sounds (e.g. in a restaurant or classroom). Importantly, there is a lot of variability between CI listeners, and it remains unclear why some people do really well with CIs, while […]
A core cognitive operation in problem solving and intelligence
Tests of simple problem solving are important because they predict success in many real life activities, including education and work. Often they are called tests of fluid intelligence. Fluid intelligence is important in meeting many kinds of cognitive challenge, such as dealing with brain diseases, mental health conditions, or developmental or economic disadvantages. Evidently a […]
A core brain network organizing thought and behaviour
Every thought or action brings together different kinds of information. If we go to the fridge for milk, we combine knowledge of the spatial layout of the kitchen, sensory input from the contents of the fridge, our goal of making tea and our knowledge of what tea requires, as well as the commands that move […]
Does decoding the brain tell us about the mind?
In the past decade, scientists have been excited about new analytical methods, using machine learning, that allow us to track information coded in patterns of brain activity. We can use them to “read” out from brain activity what participants are looking at or paying attention to, or even what they are imagining. But are the […]
Memory control in trauma’s wake
After a traumatic event, people often experience intrusive thoughts about the experience. Such memories can be powerfully distressing, so survivors of trauma typically report that they try to suppress them. Fortunately, intrusive thoughts tend to decline over time. But up to now, researchers have not known how this happens: is it merely that memories of […]
Genetic diagnosis and autistic features in young people with intellectual disabilities
Around 1% of the global population has intellectual disability (ID, also known as learning disability), meaning lifelong difficulties with cognitive functions. With recent advances in genomic technologies, it is possible to find a specific cause (genetic diagnosis) for the majority of people with severe ID. But whether and how genetic diagnosis is relevant to each […]
