Incredible piece from @thetransmitter.bsky.social on the consequences of flattening sex and gender in research🏳️‍⚧️

There's no causal influence without defined variables. Lumping the complex interplay of hormones, genes, phenotypes and socialization into one of two broad boxes is irresponsible science.
Revisiting sex and gender in the brain
To conduct scientifically accurate and socially responsible research, think of “sex” as a complex, multifactorial and context-dependent variable.

New from Theunissen group, lead by Dr. Elie

Builds on their previous work describing 11 call types in zebra finches

Here they use an auditory discrimination task to support the idea that birds categorize these as different call types

#prattle 💬
#bioacoustics
Screenshot of abstract Vocal communication in social animals involves the production and perception of various calls that ethologists categorize into call-types, based on their acoustical structure and the behavioral context of production. Whether animals perceive these categories and associate distinct meanings to them remains unknown. The zebra finch, a gregarious songbird, uses approximately 11 call-types to communicate hunger, danger, social conflict, and establish social contact and bonding. Using auditory discrimination tasks, we show that the birds discriminate and categorize all the call-types in their vocal repertoire. In addition, systematic errors were more frequent between call-types used in similar behavioral contexts than could be expected from their acoustic similarity. Thus, zebra finches organize their calls into categories and create a mental representation of the meaning of these sounds. Figure 1. The acoustic space of the zebra finch vocal repertoire. Panel A shows how the zebra finch vocal repertoire is divided into 11 distinct Etho call-types, with examples shown around a scatter plot of ~8000 call renditions from 45 birds, projected in the two first dimensions of a non-linear embedding (UMAP) applied to predefined acoustic features and color-coded according to the Etho call-type categorization. Panel B shows a confusion matrix quantifying the cross-validated performance of a supervised classifier (Linear Discriminant Analysis) at classifying calls into the Etho call-types using the spectrogram of each vocalization. Most calls are well classified, leading to high probability on the diagonal of the matrix, shown as a brighter color. The percent correct classification is obtained from the average of the diagonal. Panel C shows overlapping colored ellipses, acoustic distances derived from the probability of correct and mis-classifications in B and used in a multi-dimensional scaling (MDS) analysis to obtain a 2D projection of the acoustic space of ethogram-based call-types. The colored ellipses group call-types belonging to the same semantic hyper-category (Contact Calls: DC, LT, Te; Pair-bonding Calls: Wh, Ne; Alarm Calls: Tu, Th; Non-affiliative calls: Di, Ag; Begging calls; Courtship: Song). The spatial organization of call-types in this acoustic space (based on misclassifications of the spectrogram trained classifier) is contrasted in Fig. 4 to the spatial organization based on behavioral misclassifications (Fig. 2). Screenshot of figure 2, panel A. Photo on left shows behavioral apparatus, a perch with a pecking key and a food port below it. Schematic on right shows behavioral experiment, where apparatus waits for peck to start a new trial, with 20% of trials having a rewarded call type, and the bird is trained to interrupt non-rewarded stimuli and to not interrupt rewarded stimuli. Panel D shows whisker plot, rewarded call type vs correct classification, with raw data plots indicating males and females. The correct classification is quantified as odds ratio of correct behavioral classification. Plot shows all are above chance performance, with the mean for most around 16, i.e. 16 times more likely than chance

NIH funding generated $2.46 for every $1 funded in 2023.

Important info for scientific advocacy in the years ahead- science is a quantifiable investment, not just a cost.
