Cumulative effects of triadic closure and homophily in social networks.

Science advances

Asikainen A, Iñiguez G, Ureña-Carrión J, Kaski K, Kivelä M.
PMID: 32426484
Sci Adv. 2020 May 08;6(19):eaax7310. doi: 10.1126/sciadv.aax7310. eCollection 2020 May.

Social network structure has often been attributed to two network evolution mechanisms-triadic closure and choice homophily-which are commonly considered independently or with static models. However, empirical studies suggest that their dynamic interplay generates the observed homophily of real-world social...

PMID: 34377468
Clin Transl Immunology. 2021 Aug 03;10(8):e1323. doi: 10.1002/cti2.1323. eCollection 2021.

OBJECTIVES: The NLRP3 inflammasome plays a key role in arterial wall inflammation. In this study, we elucidated the role of serum lipoproteins in the regulation of NLRP3 inflammasome activation by serum amyloid A (SAA) and other inflammasome activators.METHODS: The...

Event-Related Potentials to Changes in Sound Intensity Demonstrate Alterations in Brain Function Related to Depression and Aging.

Frontiers in human neuroscience

Ruohonen EM, Kattainen S, Li X, Taskila AE, Ye C, Astikainen P.
PMID: 32292334
Front Hum Neurosci. 2020 Mar 27;14:98. doi: 10.3389/fnhum.2020.00098. eCollection 2020.

Measures of the brain's automatic electrophysiological responses to sounds represent a potential tool for identifying age- and depression-related neural markers. However, these markers have rarely been studied related to aging and depression within one study. Here, we investigated auditory...

Magnetoencephalography Responses to Unpredictable and Predictable Rare Somatosensory Stimuli in Healthy Adult Humans.

Frontiers in human neuroscience

Xu Q, Ye C, Hämäläinen JA, Ruohonen EM, Li X, Astikainen P.
PMID: 33935671
Front Hum Neurosci. 2021 Apr 14;15:641273. doi: 10.3389/fnhum.2021.641273. eCollection 2021.

Mismatch brain responses to unpredicted rare stimuli are suggested to be a neural indicator of prediction error, but this has rarely been studied in the somatosensory modality. Here, we investigated how the brain responds to unpredictable and predictable rare...

Percolation and spatial correlations in a two-dimensional continuum deposition model.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Asikainen J, Ala-Nissila T.
PMID: 11031543
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 May;61(5):5002-8. doi: 10.1103/physreve.61.5002.

We introduce a two-dimensional continuum deposition model of spatially extended objects, with an effective repulsive contact interaction between them represented by a parameter 0 < or = q < or = 1. For q = 0, the deposited network...

Mismatch brain response to speech sound changes in rats.

Frontiers in psychology

Ahmed M, Mällo T, Leppänen PH, Hämäläinen J, Ayräväinen L, Ruusuvirta T, Astikainen P.
PMID: 22059082
Front Psychol. 2011 Oct 28;2:283. doi: 10.3389/fpsyg.2011.00283. eCollection 2011.

Understanding speech is based on neural representations of individual speech sounds. In humans, such representations are capable of supporting an automatic and memory-based mechanism for auditory change detection, as reflected by the mismatch negativity (MMN) of event-related potentials. There...

Event-related potentials to unattended changes in facial expressions: detection of regularity violations or encoding of emotions?.

Frontiers in human neuroscience

Astikainen P, Cong F, Ristaniemi T, Hietanen JK.

Front Hum Neurosci. 2013 Sep 11;7:557. doi: 10.3389/fnhum.2013.00557. eCollection 2013.

Visual mismatch negativity (vMMN), a component in event-related potentials (ERPs), can be elicited when rarely presented "deviant" facial expressions violate regularity formed by repeated "standard" faces. vMMN is observed as differential ERPs elicited between the deviant and standard faces....
