Abstract/Results: RESULTS:
In the research project we present causal evidence from a lesion study with rare thalamic patients that the anterior ventrolateral (VL) region plays a pivotal role in linking mnemonic and attention control functions in the human brain. Subsequent fMRI work with healthy volunteers further demonstrated how the role of anterior VL thalamus in cognitive control may be shaped by experience-dependent learning, namely, in task contexts where the association between memory contents and the incoming perceptual data needs to be learned in order for memory to guide search behavior.
Together, these findings provide new and unique insight into the functional role of thalamic structures for high-level behavioral control, critically, for the biasing of attentional selection through memory and learning. The results furthermore stress the importance of characterizing the functional role of subcortical nuclei, in addition to cortical systems (e.g. parietofrontal), for a complete understanding of the mechanisms of attention and cognitive control.

Thalamic lesions impair memory guidance of visual selection
Publication year: 2011

http://www.the-bns.org/resources/11_11+BNS+Abstracts+Final.pdf
Abstract/Results: ABSTRACT:
OBJECTIVE:
Functional magnetic resonance imaging (fMRI) research suggests that guidance of attention from the contents of working memory (WM) engages a complex network including frontal areas in dorsolateral prefrontal cortex (DLPFC), superior frontal gyrus (SFG), middle temporal regions, thalamic nuclei and occipital visual cortex. However, evidence from fMRI is only correlational and therefore it is difficult to determine which of the identified brain regions are necessary and causally involved in WM guidance of attention. This issue was addressed in a lesion study with focal-lesion stroke patients.
METHODS:
A total of 67 patients were tested. Patients were required to perform a visual search task for a target object presented amongst distracters. In the valid condition the colour of the sought after target was pre-cued by a verbal cue presented prior to the search display. On neutral trials, the patients did not receive any cue prior to search. Voxel-based lesion-symptom mapping (VLSM) analyses were carried out to relate lesion anatomy to search behaviour.
RESULTS:
The VLSM analyses revealed that patients with thalamic lesions (N=4) showed no memory cueing effect of search despite having intact memory performance in a control memory task. In contrast, the control patients were able to use the memory cue to guide attention towards the target, as indexed by faster reaction times on valid relative to invalid trials.
CONCLUSION:
The findings support the role of the thalamus in controlling visual attention, specifically in guiding attention based on relevant information held in memory.

Thalamic control of human attention driven by memory and learning
Publication year: 2014

http://www.cell.com/current-biology/abstract/S0960-9822(14)00316-9
Abstract/Results: ABSTRACT:
The role of the thalamus in high-level cognition—attention, working memory (WM), rule-based learning, and decision making—remains poorly understood, especially in comparison to that of cortical frontoparietal networks [1–3]. Studies of visual thalamus have revealed important roles for pulvinar and lateral geniculate nucleus in visuospatial perception and attention [4–10] and for mediodorsal thalamus in oculomotor control [11]. Ventrolateral thalamus contains subdivisions devoted to action control as part of a circuit involving the basal ganglia [12, 13] and motor, premotor, and prefrontal cortices [14], whereas anterior thalamus forms a memory network in connection with the hippocampus [15]. This connectivity profile suggests that ventrolateral and anterior thalamus may represent a nexus between mnemonic and control functions, such as action or attentional selection. Here, we characterize the role of thalamus in the interplay between memory and visual attention. We show that ventrolateral lesions impair the influence of WM representations on attentional deployment. A subsequent fMRI study in healthy volunteers demonstrates involvement of ventrolateral and, notably, anterior thalamus in biasing attention through WM contents. To further characterize the memory types used by the thalamus to bias attention, we performed a second fMRI study that involved learning of stimulus-stimulus associations and their retrieval from long-term memory to optimize attention in search. Responses in ventrolateral and anterior thalamic nuclei tracked learning of the predictiveness of these abstract associations and their use in directing attention. These findings demonstrate a key role for human thalamus in higher-level cognition, notably, in mnemonic biasing of attention.

Assessing the role of the left dorsal frontal cortex in working memory guidance: attentional or mnemonic? A neurostimulation study
Publication year: 2019

Abstract/Results: ABSTRACT
Perceptual selection can be guided by the contents of working memory (WM). Neuroimaging and neuropsychological data points to a role of a fronto-parietal and fronto-thalamic networks in WM guidance. Here we assessed the effect of transcranial direct current stimulation of the left dorsal frontal cortex (lDFC) in a combined WM/attention paradigm. We asked the extent to which the lDFC is implicated in mnemonic and selective attention functions during WM guidance of behaviour. Observers were asked to keep information in memory while searching for a visual target, while the validity of WM contents for the search task varied. We tested the effects of lDFC-tDCS on the strength of WM guidance of search, whether any tDCS effect is dependent on the amount of WM load, and whether lDFC-tDCS primarily influences how WM contents are retained, the process of selective attention in search task, or both. Consistent with prior behavioural findings, we found that (i) selection of items that matched the contents of WM was facilitated relative to non-matching items and (ii) this WM guidance effect was reduced when the level processing/cognitive load in WM was higher. Notably, across two experiments we found that lDFC-tDCS modulated WM guidance of visual selection in the context of high processing loads in WM. No effects of tDCS were observed in WM accuracy. These findings demonstrate that the role of the left dorsal frontal cortex in WM guidance is associated with selective attentional control rather than mnemonic processing.
