Using pharmacological agents to investigate the mechanisms of the neuronal vascular coupling

The changes in cerebral blood flow, volume and oxygenation that accompany increases in neural activity form the basis of non-invasive neuroimaging techniques such as blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) which allow human brain mapping. Read more

Understanding the neural basis of ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent neurodevelopmental disorder, however the neural changes that underlie the disorder are poorly understood. Read more

Understanding neurovascular coupling and its importance in the interpretation of modern neuroimaging techniques

During the past two decades, blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) has become the scientific technique of choice for investigating human brain function in the field of cognitive neuroscience. Read more

The neurophysiological basis of spontaneous fluctuations in neuroimaging signals

A technique called blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) can determine levels of different activity in parts of the living human brain and how malfunctions can occur in disease. Read more

The breakdown of neurovascular coupling in the diseased state specifically Epilepsy and Alzheimer’s disease

Epilepsy is the most common neurological condition in the UK, affecting 1 – 2 % of the population. Epilepsies often involve only a small area of the brain - the epileptic focus – and the abnormal activity can propagate out from there. Read more

Simultaneous measures of brain and blood oxygenation: Revealing the function behind ‘functional’ brain mapping signals

A technique called blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) can determine levels of different activity in parts of the living human brain and how malfunctions can occur in disease. Read more

Neurotransmitters, brain blood flow and functional brain imaging signals.r

The function of modulatory neurotransmitter systems such as serotonin, dopamine or acetylcholine are implicated in a wide range of brain diseases and are targeted by a wide range of therapeutic drugs. Read more

Function Brain imaging in disease: what are the activation maps really telling us?

Functional brain imaging methods such as functional magnetic resonance imaging (fMRI) have already revolutionized how we can study the processes and functioning of the healthy human brain and are making an increasing impact on our understanding on what goes wrong in disease of the brain. Read more

Efficient coding in touch: Exploring cortical feature tuning in the somatosensory system through the lens of efficient coding

Efficient coding models can successfully explain the emergence of different features detectors along the visual pathway, such as center-surround receptive fields, simple and complex cells, and even higher-level visual neurons. Read more
