Neurones
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- The neurone constitutes the functional unit of the nervous system; there are over 100 billion neurones in the brain.[1,2,5] Each neurone has the ability to interact with and influence many other cells, which creat…

Anatomical regions of the brain
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- The brain is divided into four anatomical regions: the diencephalon, brainstem, cerebrum, and cerebellum, as described on the slide.[1,2] References: [1] Kandel ER, Schwartz JH, Jessell TM (eds). Principles of N…

Cerebrum
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- The cerebral cortex is the main functional unit of the cerebrum.[2] The three main functional areas of the cerebral cortex are:[1,2]

Lobes of the brain
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- The brain can be thought of as comprising five ‘lobes’ – the four lobes of the cerebral cortex and a fifth lobe, the insula, deep within the brain, as shown on the slide.[1,2,3] The lobes of the cerebral cortex ar…

Neurotransmission
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- Information moves through the nervous system via two integrated forms of communication – electrical neurotransmission and chemical neurotransmission, as shown on the slide.[1] An action potential is generated at …

The synapse
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- Neurones do not physically touch one another; two neurones are separated by a gap, known as a synaptic cleft.[1] Because neurones do not touch, and an action potential cannot ‘jump’ across a synaptic cleft, the si…

Process of chemical neurotransmission
!--?xml version="1.0" encoding="UTF-8" standalone="yes"?-- The idea that neurotransmission occurs at synapses and is mediated by chemicals was, at first, a contentious issue.[1] It was in the first half of the 1900s that experiments proved chemical neurotransmission occur…

Studying Cognitive Impairment and its Neuronal Underpinnings to Predict Illness Prognosis in Bipolar Disorder

To study intra-disease variability in cognitive function, researchers employ data-driven clustering methods to differentiate patients with widespread cognitive abnormalities from patients who are cognitively intact.

The Clinical Heterogeneity in Bipolar Disorder within Several Domains

Bipolar disorder is associated with marked clinical and phenotypic heterogeneity, including differences in symptomatology, medical and psychiatric comorbidities, and neurocognitive function. Intra- and inter-individual differences increase the complexity of the disorder, which complicates accurate diagnosis, management.

Predominant Polarity in Bipolar Disorder

Depressive predominant polarity is typically defined as having at least two-thirds of lifetime episodes being depressive, whereas manic predominant polarity refers to at least two-thirds of prior episodes being (hypo)manic episodes. Studies show that predominant polarity has prognostic value and clinical and therapeutic implications.
