“…This result falls in line with a putative involvement of low frequency oscillations in long range synchrony 40,41 . The strong theta-band coherence between FAF and CN reported in this study resembles coherence patterns between motor cortex and the dorsal striatum during attentive wakefulness 42 . The FAF constitutes a non-classical sensory area and its laminar structure (i.e.…”

Abbreviations AUC: area under the curve; BF: best frequency; CN: caudate nucleus; d: Cliff's Delta; dVS: difference in vector strength, FAF: frontal auditory field; IQR: inter-quartile range; LFP: local field potential; Med: median; PFC: prefrontal cortex; PSTH: peri-stimulus time histogram; SVM: support vector machine; VS: vector strength SummaryThe ability to vocalize is ubiquitous in vertebrates, but neural networks leading to vocalization production remain poorly understood. Here we performed simultaneous, large scale, neuronal recordings in the frontal cortex and dorsal striatum (caudate nucleus) during the production of echolocation and non-echolocation calls in bats. This approach allows to assess the general aspects underlying vocalization production in mammals and the unique evolutionary adaptations of bat echolocation. Our findings show that distinct intra-areal brain rhythms in the beta (12-30 Hz) and gamma (30-80 Hz) bands of the local field potential can be used to predict the bats' vocal output and that phase locking between spikes and field potentials occurs prior vocalization production. Moreover, the fronto-striatal network is differentially coupled in the theta-band during the production of echolocation and nonecholocation calls. Overall, our results present evidence for fronto-striatal network oscillations in motor action prediction in mammals.

“…Therefore, the slight decreases in alpha- and beta- band coherences might be due to less reward-motivated behavior toward the tasks in the rats (Sturman and Moghaddam, 2011 ; Neale et al, 2015 ). Furthermore, many studies have reported striatal LFPs modulation in the theta band during exploratory behavior (Tort et al, 2008 ; Lepski et al, 2012 ). Oscillatory activity was also observed in the delta and beta bands (Hasselmo et al, 2002 ; Lepski et al, 2012 ) as well.…”

Central thalamic deep brain stimulation (CT-DBS) has been proposed as an experimental therapeutic approach to produce consistent sustained regulation of forebrain arousal for several neurological diseases. We investigated local field potentials (LFPs) induced by CT-DBS from the thalamic central lateral nuclei (CL) and the striatum as potential biomarkers for the enhancement of lever-pressing skill learning. LFPs were simultaneously recorded from multiple sites in the CL, ventral striatum (Vstr), and dorsal striatum (Dstr). LFP oscillation power and functional connectivity were assessed and compared between the CT-DBS and sham control groups. The theta and alpha LFP oscillations were significantly increased in the CL and striatum in the CT-DBS group. Furthermore, interhemispheric coherences between bilateral CL and striatum were increased in the theta band. Additionally, enhancement of c-Fos activity, dopamine D2 receptor (Drd2), and α4-nicotinic acetylcholine receptor (α4-nAChR) occurred after CT-DBS treatment in the striatum and hippocampus. CT-DBS strengthened thalamic-striatal functional connectivity, which demonstrates that the inter-regional connectivity enhancement might contribute to synaptic plasticity in the striatum. Altered dopaminergic and cholinergic receptors resulted in modulation of striatal synaptic plasticity's ability to regulate downstream signaling cascades for higher brain functions of lever-pressing skill learning.

“…This suggests a functional connection between the frontal cortex and striatum worthy of further research. Recent research in animal models has shown increased theta coherence during attentive wakefulness, suggesting that the striatal regions play an important role in integrating multiple systems involved in cognition and motor systems [ 49 ].…”

Functional Activation during the Rapid Visual Information Processing Task in a Middle Aged Cohort: An fMRI Study

et al. 2015

View full text Add to dashboard Cite

The Rapid Visual Information Processing (RVIP) task, a serial discrimination task where task performance believed to reflect sustained attention capabilities, is widely used in behavioural research and increasingly in neuroimaging studies. To date, functional neuroimaging research into the RVIP has been undertaken using block analyses, reflecting the sustained processing involved in the task, but not necessarily the transient processes associated with individual trial performance. Furthermore, this research has been limited to young cohorts. This study assessed the behavioural and functional magnetic resonance imaging (fMRI) outcomes of the RVIP task using both block and event-related analyses in a healthy middle aged cohort (mean age = 53.56 years, n = 16). The results show that the version of the RVIP used here is sensitive to changes in attentional demand processes with participants achieving a 43% accuracy hit rate in the experimental task compared with 96% accuracy in the control task. As shown by previous research, the block analysis revealed an increase in activation in a network of frontal, parietal, occipital and cerebellar regions. The event related analysis showed a similar network of activation, seemingly omitting regions involved in the processing of the task (as shown in the block analysis), such as occipital areas and the thalamus, providing an indication of a network of regions involved in correct trial performance. Frontal (superior and inferior frontal gryi), parietal (precuenus, inferior parietal lobe) and cerebellar regions were shown to be active in both the block and event-related analyses, suggesting their importance in sustained attention/vigilance. These networks and the differences between them are discussed in detail, as well as implications for future research in middle aged cohorts.
