Attention is analyzed as the superior control system in the brain from an engineering point of view, with support for this from the way attention is presently being understood by brain science. Such an engineering- control framework allows an understanding of how the complex networks observed in the brain during various cognitive tasks can begin to be functionally decomposed. A machine version of such an attention control system is then discussed and extended to allow for goals and their reward values also to be encoded in the attention machine. The manner in which emotion may then begin to be imbued in the machine is briefly discussed and how even some glimpse of consciousness may then arise.

The first number for the year is not remarkable for any paper of striking value. Readers of the Journal will be chiefly attracted by the long and clearly written resumé of Dr. Hughlings Jackson's recent studies “On Affections of Speech from Disease of the Brain,” which is contributed by Mr. James Sully. He remarks on the great value of Dr. Jackson's attempts to classify the different forms of aphasia under the three main heads or stages of—(1) Defect of Speech, in which the patient has a full vocabulary, but confuses words; (2) Loss of Speech, in which the patient is practically speechless, and his pantomimic power is impaired as well; and (3) Loss of Language, in which, besides being speechless, he has altogether lost the power of pantomime, and even his faculty of emotional language is deeply involved in the wreck. All these states or stages again are, properly speaking, to be distinguished altogether from affections of speech in the way of loss of articulation (owing to paralysis of the tongue, &c.), or loss of vocalisation (owing to disease of the larynx); whereas the three degrees or stages of aphasia proper are due to a deep-seated and severe disorganisation of the brain. The main interest of the theory lies in the ingenious and carefully-argued analysis of the symptoms, by which Dr. Jackson arrives at the theory that as the process of destruction goes on, the superior “layers” or strata of speech fail first—those namely which involve the ordinary power of adapting sounds to the circumstances of the moment as they arise; after them fail the “more highly organized utterances” those, namely, which have in any way become automatic, such as “come on,” “wo! wo!” and even “yes” and “no,” which stand on the border-line between emotional and intellectual language; next fails the power of adapting other than vocal signs to convey an intended meaning, which is called, rather clumsily, “pantomimic propositionising;” and last of all dies out the power of uttering sounds or making signs expressive merely of emotion—a power which, of course, is not true speech at all.

High-resolution functional imaging is providing increasingly rich measurements of brain activity in animals and humans. A major challenge is to leverage such data to gain insight into the brain's computational mechanisms. The first step is to define candidate brain-computational models (BCMs) that can perform the behavioural task in question. We would then like to infer which of the candidate BCMs best accounts for measured brain-activity data. Here we describe a method that complements each BCM by a measurement model (MM), which simulates the way the brain-activity measurements reflect neuronal activity (e.g. local averaging in functional magnetic resonance imaging (fMRI) voxels or sparse sampling in array recordings). The resulting generative model (BCM-MM) produces simulated measurements. To avoid having to fit the MM to predict each individual measurement channel of the brain-activity data, we compare the measured and predicted data at the level of summary statistics. We describe a novel particular implementation of this approach, called probabilistic representational similarity analysis (pRSA) with MMs, which uses representational dissimilarity matrices (RDMs) as the summary statistics. We validate this method by simulations of fMRI measurements (locally averaging voxels) based on a deep convolutional neural network for visual object recognition. Results indicate that the way the measurements sample the activity patterns strongly affects the apparent representational dissimilarities. However, modelling of the measurement process can account for these effects, and different BCMs remain distinguishable even under substantial noise. The pRSA method enables us to perform Bayesian inference on the set of BCMs and to recognize the data-generating model in each case. This article is part of the themed issue ‘Interpreting BOLD: a dialogue between cognitive and cellular neuroscience’.

Abstract Arteriovenous malformations (AVMs) of the brain represent unique challenges for treating physicians. Although these lesions have traditionally been treated with surgical resection alone, advancements in endovascular and radiosurgical therapies have greatly expanded the treatment options for patients harboring brain AVMs. Perhaps no subspecialty within neurosurgery has seen as many advancements over a relatively short period of time as the endovascular field. A number of these endovascular innovations have been designed primarily for cerebral AVMs, and even those advancements that are not particular to AVMs have resulted in substantial changes to the way cerebral AVMs are treated. These advancements have enabled the embolization of cerebral AVMs to be performed either as a stand-alone treatment, or in conjunction with surgery or radiosurgery. Perhaps nothing has impacted the treatment of brain AVMs as substantially as the development of liquid embolics, most notably Onyx and n-butyl cyanoacrylate. However, of near-equal impact has been the innovations seen in the catheters that help deliver the liquid embolics to the AVMs. These developments include flow-directed catheters, balloon-tipped catheters, detachable-tipped catheters, and distal access catheters. This article aims to review some of the more substantial advancements in the endovascular treatment of brain AVMs and to discuss the literature surrounding the expanding indications for endovascular treatment of these lesions.

There has been increased awareness that individuals need not have a binary gender identity (i.e., male or female), but rather, gender identities exist on a spectrum. With this increased awareness, there has also been an increase in the use of they as a singular pronoun when referring to individuals with a non-binary gender identity. Has the processing of singular they changed along with a change in its usage? Previous studies have demonstrated that sentences in which they is co-indexed with singular antecedents, are judged acceptable and are easy to process, but only if the antecedents are non-referential and/or have ambiguous gender; co-indexing they with referential antecedents with unambiguous gender (e.g., Mary) results in lower acceptability ratings and greater processing effort. We investigated whether participants who frequently interacted with individuals with a non-binary gender identity and/or identified as having a non-binary gender themselves would process sentences in which themselves was co-indexed with singular antecedents similarly. We found a significant P600 effect for sentences in which themselves was co-indexed with singular referential antecedents with unambiguous gender, but failed to find a P600 effect when the antecedents were non-referential and/or had an ambiguous gender. This pattern of results is consistent with behavioural results from previous studies, suggesting that the change in the usage of singular they has not resulted in a corresponding change in the way in which this pronoun is processed.
