Working memory (WM) allows us to remember and selectively control a limited set of items. Neural evidence suggests it is achieved by interactions between bursts beta gamma oscillations. However, not clear how oscillations, reflecting coherent activity millions neurons, can individual WM Here we propose the novel concept spatial computing where cause item-specific flow spatially across network during task. This way, control-related information such as item order stored in independent detailed...
Executive control, the ability to plan one's behaviour achieve a goal, is hallmark of frontal lobe function in humans and other primates. In current study we report neural correlates executive control avian nidopallium caudolaterale, region analogous mammalian prefrontal cortex. Homing pigeons (Columba livia) performed working memory task which cues instructed them whether stimuli should be remembered or forgotten. When remember, many neurons showed sustained activation throughout period....
The present study compares the 'bandwidth of cognition' between crows and primates. Working memory is ability to maintain manipulate information over short periods time - a core component cognition. capacity working tightly limited, in humans correlated with individual intelligence commonly used synonymously cognitive capacity. Crows have remarkable skills while birds mammals share neural principles memory, its has not been tested crows. Here we report performance two carrion on paradigm...
Working memory is the cognitive capability to maintain and process information over short periods. Behavioral computational studies have shown that visual associated with working performance. However, underlying neural correlates remain unknown. To identify how affects performance, we conducted behavioral experiments in pigeons (Columba livia) single unit recordings avian prefrontal analog, nidopallium caudolaterale (NCL). Complex pictures featuring luminance, spatial color information, were...
Complex cognition relies on flexible working memory, which is severely limited in its capacity. The neuronal computations underlying these capacity limits have been extensively studied humans and monkeys, resulting competing theoretical models. We probed the memory of crows (Corvus corone) a change detection task, developed for monkeys (Macaca mulatta), while we performed extracellular recordings prefrontal-like area nidopallium caudolaterale. found that encoding maintenance information were...
<title>Abstract</title> The saying "context is everything" underscores the importance of interpreting things, be they quotes, events, actions, or stimuli, not in isolation but light a bigger picture - their context. This evident even fundamental forms learning such as extinction where, contextual renewal, an extinguished response reoccurs if context changed. But what exactly context? Is given by stimuli with inherent properties making them or, are circumstances that allow stimulus to become...
Color vision is an important perceptual ability in most species and a crucial capacity underlying any cognitive task working with color stimuli. Birds are known for their outstanding tetrachromacy. Two jackdaws were trained to indicate whether they perceive two colors as same or different. The dominant wavelengths of the experimental assessed relate birds' performance physical qualities results that differences similarities had strong influence on behavioral data. Colors related reduced...
Extinction learning does not erase previously established memories but inhibits the expression of fear by formation new memory traces that are strongly context-dependent. Previous human neuroimaging studies using representational similarity analysis revealed several core properties during learning, including their tendency to generalize beyond initial context – a process described as “cue generalization” and reliance on sensory rather than conceptual formats. How altered extinction however,...

Abstract The ability to direct attention and select important information is a cornerstone of adaptive behavior. Directed supports cognitive operations underlying flexible behavior, for example in extinction learning, was demonstrated behaviorally both mammals birds. neural foundation such endogenous attention, however, has been thoroughly investigated only still poorly understood And despite the similarities at behavioral level, cognition birds evolved parallel over 300 million years,...
Context-dependent extinction learning enables organisms to acquire an inhibition of responding cues that no longer signal reward in specific environmental settings. Both the hippocampus and prefrontal cortex play key but complementary roles encoding extinction. To understand what drives differential contributions these two structures, we recorded single-unit responses from pigeon (HPC) like nidopallium caudolaterale (NCL), while animals were engaged a repeated appetitive ABA paradigm. HPC...
Abstract Executive functions arise from multiple regions of the brain acting in concert. To facilitate such cross-regional computations, is organized into distinct executive networks, like frontoparietal network. Despite similar cognitive abilities across many domains, little known about networks birds. Recent advances avian fMRI have shown a possible subset regions, including nidopallium caudolaterale (NCL) and lateral part medial intermediate (NIML), that may contribute to complex...
