The functional characterization of callosal connections [PDF]
Progress in Neurobiology, 2022 The brain operates through the synaptic interaction of distant neurons within flexible, often heterogeneous, distributed systems. Histological studies have detailed the connections between distant neurons, but their functional characterization deserves further exploration.

On connected Boolean functions [PDF]
Discrete Applied Mathematics, 1999 AbstractA Boolean function is called (co-)connected if the subgraph of the Boolean hypercube induced by its (false) true points is connected; it is called strongly connected if it is both connected and co-connected. The concept of (co-)geodetic Boolean functions is defined in a similar way by requiring that at least one of the shortest paths connecting

The genetic architecture of language functional connectivity [PDF]
NeuroImage, 2021 AbstractLanguage is a unique trait of the human species, of which the genetic architecture remains largely unknown. Through language disorders studies, many candidate genes were identified. However, such complex and multifactorial trait is unlikely to be driven by only few genes and case-control studies, suffering from a lack of power, struggle to ...

Regularized Functional Connectivity in Schizophrenia
Frontiers in Human Neuroscience, 2022 Regularization may be used as an alternative to dimensionality reduction when the number of variables in a model is much larger than the number of available observations. In a recent study from our group regularized regression was employed to quantify brain functional connectivity in a sample of healthy controls using a brain parcellation and resting ...

Functional Connectivity in Aging [PDF]
, 2019 A large body of research shows that aging is accompanied by localized changes in brain structure and function. However, over the past decade the neuroimaging community has begun to recognize the importance of investigating the brain as a network.

Nonequilibrium Green’s Functions for Functional Connectivity in the Brain [PDF]
Physical Review Letters, 2021 A theoretical framework describing the set of interactions between neurons in the brain, or functional connectivity, should include dynamical functions representing the propagation of signal from one neuron to another. Green's functions and response functions are natural candidates for this but, while they are conceptually very useful, they are usually

Functional Connectivity of the Cognitive Cerebellum [PDF]
Frontiers in Systems Neuroscience, 2021 Anatomical tracing, human clinical data, and stimulation functional imaging have firmly established the major role of the (neo-)cerebellum in cognition and emotion. Telencephalization characterized by the great expansion of associative cortices, especially the prefrontal one, has been associated with parallel expansion of the neocerebellar cortex ...

The functional logic of corticostriatal connections [PDF]
Brain Structure and Function, 2016 Unidirectional connections from the cortex to the matrix of the corpus striatum initiate the cortico-basal ganglia (BG)-thalamocortical loop, thought to be important in momentary action selection and in longer-term fine tuning of behavioural repertoire; a discrete set of striatal compartments, striosomes, has the complementary role of registering or ...

Connectivity functions and polymatroids
Advances in Applied Mathematics, 2016 A {\em connectivity function on} a set $E$ is a function $ :2^E\rightarrow \mathbb R$ such that $ (\emptyset)=0$, that $ (X)= (E-X)$ for all $X\subseteq E$ and that $ (X\cap Y)+ (X\cup Y)\leq (X)+ (Y)$ for all $X,Y \subseteq E$. Graphs, matroids and, more generally, polymatroids have associated connectivity functions.

Functional connectivity patterns in parosmia
Behavioral and Brain Functions, 2023 Abstract Objective Parosmia is a qualitative olfactory dysfunction presenting as “distorted odor perception” in presence of an odor source. Aim of this study was to use resting state functional connectivity to gain more information on the alteration of olfactory processing at the level of the central nervous system level.
